Complete State-Space Digital Computer Simulation of Chopper-Fed DC Motors

This paper considers a computer-simulated system comprising a nonlinear dc motor pulse fed from a thyristor controller. Simulated steady-state and transient performance from a general circuit simulation program allows the stability of a motor design and characteristics of a controller to be predicted and judged. All chopper circuit semiconductor static and dynamic electrical requirements plus motor losses can be determined for any imposed mechanical load conditions. A current-impulse commutated dc chopper/controlled compound motor simulation is presented and results correlate excellently with those obtained experimentally.
