Abstract

A lower cost Auxiliary Power Unit (APU) of series hybrid bus based on diesel engine, permanent magnet synchronous motor and uncontrolled rectifier is presented in this paper. On the basis of a built system model, and according to static data, an APU power closed-loop controller which is consisted of forward-control circuit and PID feedback-control structure is developed. The simulation results show that, better dynamic characteristics of power output for the lower cost auxiliary power unit of hybrid bus is realized, with the forward and PID control method, and to a certain extent, meanwhile the stability of engine speed is guaranteed.
