ABSTRACT:
In a control system for a reluctance motor driving a load, the output of a reference waveform generator is applied to a power converter through a current controller. The output of the generator is determined by rotor position, as detected by a sensor. The generator establishes a relative magnitude for motor phase current for every position of the rotor during the period of energization of a motor phase. A further control input may determine the absolute magnitude of the motor phase current, subject to the waveform pattern established by the generator. The reference waveforms may be sinusoidal. A method of determining the configuration of suitable reference waveforms for a given motor involves monitoring selected parameters of motor operation while controlling other such parameter in a test procedure.
