Hardware-in-the-loop Simulation on Dynamical Coordinated Control Method in Parallel Hybrid Electric Vehicle(PHEV)

在指出并联式混合动力汽车(Parallel hybrid electric vehicle,PHEV)发动机与电动机动力耦合过程中存在的协调问题基础上,提出基于模型匹配控制的动态协调控制方法,开发出双驱动电动机结构的硬件在环仿真试验平台硬件系统和基于Matlab/Simulink/RTWT与Visual C++环境的软件系统,并建立PHEV动态协调控制方法硬件在环仿真试验台。对所设计的动态协调控制方法进行硬件在环仿真试验,试验结果表明,该动态协调控制方法能有效控制两个动力源的动力耦合过程,具有较高的转矩控制精度和很好的动态响应特性。

To deal with the coordinated issue between motor and engine of parallel hybrid electric vehicle, a dynamical coordinated control method based on the model-match-control method is designed. The hardware-in-the-loop simulation test bench for studying on the dynamical coordinated control method is established, including the hardware system of dual driven motors and the software system based on the Matlab/Simulink/RTWT and V＇tsual C＋＋ developing system, The control method is validated by experiment through the hardware-in-the-loop simulation test bench. The results show that the dynamical coordinated control method which has high torque control accttracy and very good dynamic response characteristics can effectively control the coupling process between motor and engine.
