Abstract:

Digital control system design has been popular in the aerospace and process control industries. Advances in microprocessor technologies have added new growth to this popularity. The use of microprocessor-based systems for control purpose places new demands on digital control thoery. Since microprocessors are relatively slow digital machines and usually have small work lengths, it is necessary to place importance quantizarion with respect to the control system. The wind length and speed of the signal processing components Analog-to-Digital AD and Digital-to-Analog DA converters placed additional constriants on the digital control system performance. In order to be able to analyze the effects of constraints that are involved in microprocessor-based control system design, it will be necessary to develop a basic system and a set of procedures that are modifiable to a variety of control configurations. The subject of this thesis is the design, development, and analysis of a 16-bit microprocessor based digital control system. The prupose of the study is threefold 1 To show that a hybrid computer system, consisting of 16-bit single board microcomputer and an analog computer, can be used effectively for digital control studies 2 To evaluate the frequency response of the hybrid system and 3 To identify and evaluate the error contributors which can effect the performance of digital control systems. Keywords MC68000 microprcessor, TMS32010 microprocessor, Tustin algorithm, and Rattan algorithm.
