摘　　要：研究车载牵引控制优化问题,针对克服机车牵引控制器车载测试存在的针对误差较大和不同步的弊端,提出设计实际控制器与虚拟被控对象相结合的牵引控制器测试模式。根据dSPACE实时仿真器建立了牵引逆变器和牵引电机的实时仿真模型,对仿真器的采样步长与控制器的事件步长不同步而导致的采样延迟,采用了一种补偿算法,有效消除了因采样延迟产生的仿真误差。对建立的牵引逆变系统实时仿真模型的正确性进行仿真。结果证明了补偿算法的有效性。实时仿真模型已应用于牵引控制器的研发与测试,取得了较好的效果。To overcome the disadvantages of vehicle testing of locomotive traction controller,the ＂real controller and virtual controlled object＂ test mode is brought.The models of the traction inverter and the traction motor are built based on dSPACE real-time simulator.A new compensation algorithm is shown to eliminate the errors caused by sampling delay which is produced by non-synchronous sampling steps of the simulator and the controller.The test results have proved the correctness of the real-time simulation system and the compensation algorithm is confirmed by the comparative tests.The system has been used to develop and validate the traction controllers and has made a success.
