...John Hauser Department of EE-Systems University of Southern California Los Angeles, CA 90089–0781 Memorandum No. UCB/ERL M91/46 29 April 1991 Electronics Research Laboratory College of Engineering University of California, Berkeley 94720 A Case Study in Approximate Linearization: The Acrobot Example Richard M. Murray∗ Electronics Research Laboratory University of California Berkeley, CA 94720 murray@united.berkeley.edu John Hauser† Department of EE-Systems University of Southern California Los Angeles, CA 90089–0781 hauser@nyquist.usc.edu 29 April 1991 Abstract The acrobot is a simple mechanical system patterned after a gymnast performing on a single parallel bar. By swinging her legs, a gymnast is able to bring herself into an inverted position with her center of mass above the part and is able to perform manuevers about this configuration. This report studies the use of nonlinear control techniques for designing a controller to operate in a neighborhood of the manifold of inverted equilibrium points. The techniques described here are of particular interest because the dynamic model of the acrobot violates many of the necessary conditions required to apply current methods in linear and nonlinear control theory. The approach used in this report is to approximate the system in such a way that the behavior of the system about the manifold of equilibrium points is correctly captured. In particular, we construct an approximating system which agrees with the linearization...

...around us. Leonard explains to the reader how the Chaos Theory works through mathematical diagrams, models, and simulations to show the possible results the theory could claim on the environment around us. The book is for the most part easy to understand and gives the reader a sufficient understanding even if the reader does not have a background in mathematics or science. Chaos theory first came about when scientist decided they wanted to be able to predict the future more accurately of certain events happening. The theory takes a look at the initial beginning of a system and tries to determine its future behavior. The system is for the most part random yet has a deterministic quality because the initial conditions already lay out the future of the system and is defined by those initial conditions with no chance of randomness. Leonard points out three chaotic mathematical systems and they are; chaotic systems are non-linear, deterministic, and unstable in that they display...

...as load-flow study, is an important tool involving numerical analysis applied to a power system. A power flow study usually uses simplified notation such as a one-line diagram and per-unit system, and focuses on various forms of AC power (i.e.: voltages, voltage angles, real power and reactive power). It analyzes the power systems in normal steady-state operation. A number of software implementations of power flow studies exist. In addition to a power flow study, sometimes called the base case, many software implementations perform other types of analysis, such as short-circuit fault analysis, stability studies (transient & steady-state), unit commitment and economic load dispatch analysis. In particular, some programs use linear programming to find the optimal power flow, the conditions which give the lowest cost per kilowatthour delivered. Power flow or load-flow studies are important for planning future expansion of power systems as well as in determining the best operation of existing systems. The principal information obtained from the power flow study is the magnitude and phase angle of the voltage at each bus, and the real and reactive power flowing in each line. Commercial power systems are usually too large to allow for hand solution of the power flow. Special purpose network analyzers were built between 1929 and the early 1960s to provide laboratory models of power systems; large-scale digital computers replaced the analog...

...Prototyping Excavator Control Systems Mark D. Elton, Aaron R. Enes, and Wayne J. Book, Fellow, IEEE Abstract— A multimodal operator interface station is developed to display a realistic virtual reality depiction of a compact excavator performing general digging tasks. The interface station includes engine audio feedback and a near life-size operator display attached to a full-size cab. The excavator dynamics are determined by models of the hydraulic system, the linkage system, and the soil digging forces. To maximize the fidelity of the hydraulic model, certain “virtual” components of the model are replaced with real-time hardware-in-the-loop (HIL) simulations of the actual hardware. HIL simulation is done in a geographically isolated facility, with Internet based communication between HIL and the Remote Operator Interface. This is the first reported high-fidelity operator interface to be combined with remote hydraulic HIL simulations. I. I NTRODUCTION Hydraulic hardware has undergone a great evolution in recent years, evolving from purely hydro-mechanical devices to electro-hydraulic systems controlled by microprocessors. The use of electronic controllers opens the door to improving dynamic performance and enhancing traditional hydraulic off-highway construction machines with new features such as increased energy efficiency, improved operator controllability, and overall increases in productivity. With these added capabilities often comes added system complexity, particularly...

...have to be quantified and do not have to be financial - Strategies define how organizations should use their resources to meet these objectives – a well-conceived strategy guides employees in successfully pursuing their organizations’ objectives; it conveys to employees what they are supposed to be doing - Strategic control involves managers addressing the question: Is our strategy valid/is our strategy still valid, and if not, how should it be changed? - Management control focuses on execution and it involves addressing the general question: Are our employees likely to behave appropriately? Do our Employees understand what we expect of them? Will they work consistently hard and try to do what is expected of them (will they pursue the organization’s objectives in line with the strategy)? Are they capable of doing a good job? - Managers addressing strategic control issues have a focus primarily external to the organization; they examine the industry and their organization’s place in it - Managers addressing management control issues have a primarily internal focus; they reflect how they can influence employees’ behaviors in desired ways Causes of Management Control Problems 1.

...Topic 4.Controlling Topic 1: What is Control and Why Engage in It? Introduction Many people think of the word “control” in the context of manipulating someone or something. They think of control as getting someone to do something that WE want them to do, and it follows that they may NOT want to do it! In management, control has a different meaning. It is simply an information system that provides valuable feedback. In your textbook, control is defined as “the process of monitoring activities to ensure that they are being accomplished as planned and correcting any significant deviations” (Robbins et al., page 308). In other words, you measure the results you are getting and compare this with your objectives and then make any necessary adjustments. Managers who control the finances of an organization are often referred to as “controllers.” These managers use financial control measures on a daily basis. Project managers also use control mechanisms to monitor their projects. Control measures are determined at the beginning of a project and used throughout the life of a project to monitor time, budget, and project scope. The control measures give the project team valuable feedback on how they are doing. Just as feedback is a critical component in good communication, feedback is also a key factor in developing management controls. Measurement controls can be set up in virtually any area of an organization. One area that most people have experience with is the annual performance...

...Adaptive Traffic Control System Performance measure against which our proposed policy to be tested is green time utilization. This performance measure is estimated by measuring the green time during which vehicles are served for an instance of a given phase and then dividing by the total length of the green time instance (i.e. minimum and maximum green time) The supporting data for green time utilization are as follows: * Allocated minimum and maximum green time * vehicle departure times * Saturation headway These data can be retrieved from the Signal control data and stop line detector. Our objective is to maintain ideal state as long as possible if control system deviates from this ideal state to (over-utilization) or (under-utilization) then by using adaptive control strategy system will take actions by changing existing policy. Objective: max.8≤Ugfk<1 Subject to constraints: g minfk≤gfk≤g maxfk (1) f=AFgfk≤C (2) Here, Ugf= Average time taken by vehiclesAvailable time Ugf=number of departures in phase f× hsat{gmin, gmax} Ugminf= number of departures in phase f× hsat{gmin}, Ugmaxf= number of departures in phase f× hsat{gmax} So, theoretically the green time utilization should follow following condition to be remain in ideal...

...President of any new internal control requirements if the company decides to go public. (7 points) Instituting a system of internal checks and balances would be foremost in my recommendations to the company president since most internal control systems provide for independent internal verification; this principle involves the review of data prepared by employees. To obtain maximum benefit from independent internal verification: * Companies should verify records periodically or on a surprise basis. * An employee who is independent of the personnel responsible for the information should make the verification. The company should also look at incorporating a Voucher Control System. Most medium and large companies use vouchers as part of their internal control over cash disbursements. A voucher system is a network of approvals by authorized individuals, acting independently, to ensure that all disbursements by check are proper. When looking to hire new employees, it is vital that the company utilize the extensive resources on the web in providing for complete background investigations. A lot of wasted time and energy could be recouped using effective human resource controls. Effective web access controls could likewise prevent embarrassing behavior and lost company time on the part of current employees (i.e. downloading porn, idle surfing/shopping, etc.). More oversight of the petty cash fund would also certainly be in order. “Internal control over a petty cash fund is...
