To solve the contradiction between interior space and demand for electricity of vehicle, this paper brings forward the dual-generator parallel power system (DPPS). However, it is difficult to control the voltage and balance output power between two different types of generators simultaneously. Thus, feed-forward control has been developed to accomplish decoupling the target current of two generators, and proportional-integral-differential (PID) controllers, with its stability being discussed, are also designed to track desired values. Based on structural analysis of DDPS, the simulation model is built in MATLAB/Simulink to prove the preliminary feasibility of the scheme and provide a reference for the real system. Finally, bench tests have been performed involving the dynamic change in the reference voltage, engine rotating speed, and load, to verify the effectiveness of the proposed method. The results show that it can achieve synchronous control of the output voltage and current ratio of two generators in DPPS.

使用前馈去耦控制车辆中的DPPS

为了解决内部空间与车辆电力需求之间的矛盾，提出了双发电机并联动力系统（DPPS）。然而，难以同时控制电压和平衡两种不同类型的发电机之间的输出功率。因此，已经开发了前馈控制来实现两个发电机目标电流的去耦，并且还讨论了比例积分微分（PID）控制器（讨论了其稳定性）以跟踪所需值。基于DDPS的结构分析，在MATLAB / Simulink中建立了仿真模型，以证明该方案的初步可行性，为实际系统提供参考。最后，进行了基准电压，发动机转速和负载的动态变化的台架试验，验证所提出方法的有效性。结果表明，它可以实现DPPS中两台发电机的输出电压和电流比的同步控制。
