ABSTRACT:
A control system for a multi-phase synchronous machine having a shaft driven at variable speed or for developing a variable torque angle includes shaft angular position detectors that derive first and second output pulses respectively representing a shaft angular displacement corresponding with each pole of the machine and a predetermined shaft angular displacement within each pole. In response to a plurality of the second output pulses, a frequency locked loop derives a variable frequency pulse output. Individual pulses are selectively inserted and deleted from the variable frequency output to derive a variable phase pulse output representing machine torque angle. A triangle up/down counter responds to the variable phase output to derive a pulse output signal having a frequency that is a submultiple of the variable frequency output and a phase determined by the phase of the variable phase output. The time position of pulses of the first output and the up/down counter are compared to control the insertion and deletion of the individual pulses. Each phase of the machine is driven in response to the output signal of the triangle up/down counter.
