Abstract
A system to control the fixed mass/spring mechanical resonance of the motor in conjunction with a model of the motor that estimates the present position and allows the determination of the motor stator voltage pattern which will produce the requested output force. This approach effectively eliminates the electrical restoring force from the motor dynamics and minimizes the problems associated with the varying resonant frequency of the motor.
