Controlling Strategies to Reduce Torque Ripple in Switched Reluctance Motor in Series Hybrid Electric Vehicle 2017-26-0089

Switched reluctance motor (SRM) are gaining wider popularity among variable-speed applications. This is due to their simple, low-cost construction characterized by an absence of magnets and rotor winding, high level of performance over a wide range of speeds, and fault-tolerant power stage design. Availability and the moderate cost of the necessary electronic components make SRM a viable alternative to other commonly used motors like AC, BLDC, PM Synchronous or universal motors for numerous applications. Switched reluctance motor’s (SRM) double salient structure makes its magnetic characteristics highly nonlinear. The motor flux linkage and generated electric torque is a nonlinear function of stator currents as well as rotor position. All these make the control of the SRM a tough challenge. This thesis attempts to investigate the different controlling strategies for switched reluctance motor from the motor’s structure properties, model equations, and operation principle. These controlling strategies are Proportion Integral and Derivative (PID) and Sliding Mode Control (SMC).
The performance comparison is done through rigorous Matlab/Simulink simulations.6/4 switched reluctance motor’s Nonlinear model is implemented for investigation.
