Abstract: The current work illustrates a mathematical analysis and simulation of an AC electric drive control system with variable moment of inertia. A three-phase induction motor is used in this control system. A mathematical model for this motor is developed. This mathematical model has been tested in MATLAB/Simulink. A new closed-loop control system for this AC electric drive system is proposed. The proposed control system is based on the technical optimum method of design. The controlled variable of this system is the load angular speed. In the developed electric drive control system the moment of inertia is variable. It is considered as a function of time. Also in this model the load torque is considered to be a variable as a function of angular speed. A controller is designed for the reduced order model to meet desired performance specifications by using the technical optimum method. This controller is attached to the reduced order model and the closed-loop response is observed. The parameters of the controller are tuned to obtain a response with desired performance specifications.
