基于dSPACE的混合动力轿车AMT电机控制系统

在开发混合动力轿车电机驱动的AMT(机械式自动变速器,AutomatedManualTransmission)过程中,一项重要的工作就是对选档、换档和离合器驱动电机的调节与控制。文章通过建模工具MATLAB/Simulink建立了电机PID控制算法和控制系统模型;采用DS1401/1501的dSPACE实时仿真环境自动生成控制器实时代码。dSPACE的实时仿真系统具有与被控系统的硬件接口,可以与实际电机系统直接相连。通过这个仿真平台构成实现了AMT的HIL(硬件在回路,HardwareIntheLoop)仿真测试系统。在此基础上分析了电动机的控制方法,最后给出了实验测试结果。该系统已应用于混合动力轿车的开发中。

dSPACE Based Motor Control System of Hybrid Electrical Vehicle AMT

In the process of developing motor drived AMT(Automated Manual Transmission) of Hybrid Electrical Vehecle,one of the key work is to adjust and control the selecting motor,the gear shifting motor and the clutch motor.Here,with MATLAB/Simulink,the PID controlling arithmetic and the controlling system models of the moters are built.For the real-time code can be generated with the dSPACE Rea-Time Workshop DS1401/1501,and the workshop has hardware interface with the controlled systems,it can be directly connected to the actual system.With the workshop a HIL(Hardware In the Loop) simulating and testing system of the AMT is implemented.It can be used to analyze motor control method.At last,some test results are illustrated.The system has been successfully apply to the development of a Hybrid Electrical Vehecle.
