Ripple reduced control of switched reluctance motor drives

Nowadays switched reluctance motor (SRM) drives have been widely used in the field of controlled electric motor drives. The paper proposes a simple control method for SRM drives. The main goal of the drive control is to improve dynamical performance by compensating for the motor nonlinearities. The ripple free operation can be realize only with an current waveform depending on the angle, speed and torque. The proposed ripple reduced method changes only the turn-on and the turn-off angle in function of the speed and current reference. One off the advantages of using the ripple –reduced method that it does not need the real-time calculation or measuring the motor torque. So it can be implemented on a cheap microcontroller. The test of this control method was performed in an experimental drive system. A SRM of 6/8 pole and 4 kW rated power was used. Simulation and experimental results are presented
