Investigation of Model Reference Parameter Adaptive SRM Drives

Nowadays switched re luctance motor (SRM) drives have been widely used in the field of controlled electric motor drives. The paper proposes a m odel reference adaptive control method for SRM drives. The main goal of the drive control is to improve dynamical performance by compensating for the motor nonlinearities. The r ipple free operation can be realize only w ith an current waveform depending on the angle, speed and torque. The proposed ripple reduced meth od changes only the turn-on and the turn-off angle in functio n of the speed and current reference. One of 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 d rive system. A SRM of 6/8 pole and 4 kW rated power was used. Simulation and experimental results are presented
