This thesis considers the construction of an expert system for computer aided control system design. The contributions of the thesis are: implementing the first expert system for computer aided control system design; developing a heuristic approach for lead-lag compensation of single-input, single-output systems; stating some traits of a human expert in control system design, creating an architecture for an expert system for control system design; representing in a rule-based expert system a heuristic approach to the design of lead-lag compensation for single input, single output continuous linear systems, sampled data linear systems, and nonlinear system; coordinating the symbolic computations of the inference engine with the numeric computations of the external programs; providing the nonmonotonic reasoning required by design revisions; checking the consistency of reason maintenance rules that implement nonmonotonic reasoning; and constructing the knowledge sources for design. Examples of applying the knowledge bases to the design of control systems are provided; and examples are given of the rules used to represent the knowledge and of the rules was to guide the development of the problem solution.
