  • Computers now form an integral part of most real-time control systems.With the advent of the microprocessors and microcontrollers in the last few decades the use of computers in control applications has been ever growing. Microcontrollers are single-chip computers which can be used to control real-time systems. Such controllers are also referred to as embedded real-time computers. These devices are low-cost, single-chip and easy to program.

  • Abstract: Industry standard for the control of switch mode power supply (SMPS) systems has been analog control. Now with the advent of high speed, lower cost digital signal processing (DSP) ICs, digital control there has been an increased interest in digital control of SMPS. The Power Electronics & Power Quality Laboratory of Texas A&M University is currently exploring several implementation aspects of digital control of power factor correction (PFC) stage of SMPS. Two low cost digital controllers: TMS320LF2407 and ST52x420 are evaluated for implementing PFC function.

  • The NASA Mars Sojourner rover inspired this project . I followed the mission with great enthusiasm and witnessed a giant leap in robotics that day it began roaming the Martian terrain and sending images back to earth. Though I was in awe when the Viking missions of the 1970’s were in progress, we didn’t see that near real-time interaction with the craft .

  • Today’s control system designers face an ever-increasing “need for speed” and accuracy in their system measurements and computations. New design approaches using microcontrollers and DSP are emerging, and designers must understand these new approaches, the tools available, and how best to apply them. This practical text covers the latest techniques in microcontroller-based control system design, making use of the popular MSP430 microcontroller from Texas Instruments.

  • A PLC or programmable controller is a computer based solid state device that controls industrial equipment and processes. Initially designed to perform the logic functions executed by relays, drum switches and mechanical timer/counters, it has been extended to analog control as well. A typical PLC system consists of a processor and an input/output system all mounted in a rack like system. The PLC system is a cost effective solution for applications with a high ratio of digital to analog points in a system.

  • This book will discuss the topic of Control Systems, which is an interdisciplinary engineering topic. Methods considered here will consist of both "Classical" control methods, and "Modern" control methods. Also, discretely sampled systems (digital/computer systems) will be considered in parallel with the more common analog methods. This book will not focus on any single engineering discipline (electrical, mechanical, chemical, etc), although readers should have a solid foundation in the fundamentals of at least one discipline....
