Abstract

A diesel-generator can be applied to electric vehicle as an auxiliary power unit (APU). As for its generator, an excitation control method without the brushless exciter parameters is presented. Its first order lag model is obtained through the step response at zero engine speed with the Ziegler-Nichols method. And a PI controller comes out. Then the PI parameters are tuned by simulation and static experiments. At last, the PI excitation regulator is validated by both engine speed and APU voltage regulation experiments on the dSPACE controller. The results are satisfied
