PD, PI, and PID controller designing software using MATLAB

Includes bibliographical references.The main purpose of this project is the design and programming of software which designs PD, PI and PID controllers for a plant transfer function, given a user specified desired output phase margin and error H9constant as design parameters. The controllers to be designed are restricted to controllers in series with the controlled process, with unity feedback. Frequency domain analysis techniques are used as the basis for the controller design algorithm, the methods of which are derived from the reference texts listed, and outlined in this document. The project software is written in MATLAB, to take advantage of many of its existing controls based frequency domain analysis functions, and to provide a medium for full exploitation and analysis of the software I s design results.B.S.
