| | Investigation Of Model Reference Parameter Adaptive Srm Drives
By Laszlo Szamel | |

Abstract: Nowadays switched reluctance motor (SRM) drives
have been widely used in the field of controlled electric motor
drives. The paper proposes a model 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 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 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 drive system. A SRM of 6/8 pole
and 4 kW rated power was used. Simulation and experimental
results are presented.
