MATLAB simulation of a multi-level speed control system of a 6/4 SRM using PI controller

The speed control of a switch reluctance motor (SRM) using feedback control method with the help of a proportional integral (PI) controller is presented in this paper. The paper proposes the design of a PI controller for a 6/4 SRM under different load conditions. The control mechanism is designed such that the motor runs at half of the rated speed for first few cycles and then attains the rated speed for the remaining cycles. The values of the controller gains Kp, Ki are tuned in such a way that the rated speed is maintained under different operating conditions. MATLAB Simulink is used to illustrate the simulation results for the motor at zero, half and full load conditions. The simulation results are compared and analyzed.
