The state-space analysis of excitation regulation of self-controlled synchronous motor with constant margin-angle control

摘要

A mathematical model of the self-controlled synchronous motor with finite DC inductor and main flux saturation effects considered is established, and its steady-state performance under constant margin-angle control is investigated on the basis of simulated waveforms. The mechanical characteristics and the corresponding excitation regulation, which ensures that the motor operation is stable, are obtained.
