The work, of which this thesis is a record, is concerned with the development of a microprocessor based system to simulate, at a speed approaching real time, the steady state and transient response of induction motor drives under various conditions. This development proceeds by outlining the basic theory involved in the simulation of induction motors. This is followed by an analysis of the various integration methods available for the solution of ordinary differential equations. This analysis being primarily concerned with determining the most efficient means of solving the set of equations used to describe induction motor response. The third part of this work explains the development of a distributed processing system that was used to achieve the simulation. This part of the work starts by describing the procedures that were followed in the development of a single processor-co-processor system and continues to detail the extension from one microprocessor to four in order to increase the speed of solution.
