  • A control system is a collection of components working together under the direction of some machine intelligence. In most cases, electronic circuits provide the intelligence, and electromechanical components such as sensors and motors provide the interface to the physical world. A good example is the modern automobile. Various sensors supply the on-board computer with information about the engine’s condition. The computer then calculates the precise amount of fuel to be injected into the engine and adjusts the ignition timing. T...

  • Despite the great technological advancement experienced in recent years, Programmable Logic Controllers (PLC) are still used in many applications from the real world and still play a central role in infrastructure of industrial automation. PLC operate in the factory-floor level and are responsible typically for implementing logical control, regulatory control strategies, such as PID and fuzzy-based algorithms, and safety logics. Usually PLC are interconnected with the supervision level through communication network, such as Ethernet networks, in order to work in an integrated form....

  • Process control is an application area of chemical engineering - an identifiable specialty for the ChE. It combines chemical process knowledge (how physics, chemistry, and biology work in operating equipment) and an understanding of dynamic systems, a topic important to many fields of engineering. Thus study of process control allows chemical engineers to span their own field, as well as form a useful acquaintance with allied fields. Practitioners of process control find their skills useful in design, operation, and troubleshooting - major categories of chemical engineering practice....

  • The use of a combustion engine to motivate a car has been questioned in recent times due to the increasing concern of warming. As a result of this, the concept of driving a car with an electric engine has become of particular interest. Dr. Geoff Walker and his PhD students are working on the creation of the Universitys own electric car. This thesis project is focused on deriving a control scheme to drive an induction machine that could be applied to the electric car.

  • This manual supports you when you work with the temperature controller block from the Standard Library PID Control. It will familiarize you with the functions of the controller blocks and, in particular, with tuning the controller and working with the user interface in which you set the parameters for the blocks. There is an online help system for both the blocks and the user interface that supports you when setting the parameters of the blocks. This manual is intended for qualified personnel involved in programming, configuration, commissioning, and servicing of programmable controllers.

  • Welcome to Network Access Control For Dummies. It's a scary networking world out there, and this book provides you with a working reference for understanding and deploying what type of network access control (NAC) is best suited for your network and you. Because you're holding this book, you already know that security issues exist out there — and you've probably, maybe frantically, attempted to protect the network you're responsible for from the scenarios that get printed on the front page....

  • This book reports initial efforts in providing some useful extensions in financial modeling; further work is necessary to complete the research agenda. The demonstrated extensions in this book in the computation and modeling of optimal control in finance have shown the need and potential for further areas of study in financial modeling. Potentials are in both the mathematical structure and computational aspects of dynamic optimization. There are needs for more organized and coordinated computational approaches.

  • Custom controls and Web Parts can make you more productive by enabling you to create re-usable components for your WebForms. You can package up a piece of your user interface and re-use it within your Web site or across many Web sites. But that’s only one way that these controls make you more productive. If you’ve ever had an ASP.NET control that you wished worked slightly differently, you can now create the control that you want. When you build your own custom controls and Web Parts, you can have the control do as much (or as little) as you want....

  • SERVICE PROCESS KAIZEN: ADOPTING PROCESS STABILIZATION METHODS TO CONTROL SERVICE WORK FLOW AND TO IMPROVE CUSTOMER SERVICE I drop MSAs that are not in SAT states or where available completion rate data cover less than two thirds of public enrollment. This leaves a sample of 931 districts from 50 MSAs. In spite of the serious limitations in the CCD data, the pattern of results in Panel D is quite similar to that in Panel C. Again, the student quality index is a strong predictor of completion rates, but its coefficient is (insignificantly) smaller in high-choice than in low-choice MSAs....

  • This work is an extension to the earlier publication Instrumentation Fundamentals for Process Control (2001) in which the basics of instrumentation were given along with some applications of instruments and control systems to real processes. Because the present work is an extension of this latter aspect, it is therefore confined mainly to the techniques of applying instrumentation and control systems to manipulate the process to give the desired results.
