摘　　要：为了降低永磁同步电机的转矩波动,提高系统趋近速度自适应调节的能力,进而减少系统能量消耗,提高新能源电动汽车的续航能力,设计了一种新型滑模趋近律。并将新型趋近律下的控制系统与传统滑模控制系统及PI控制系统进行了比较。在基于TMS320F28335搭建的硬件电路上对新型滑模控制算法进行了验证。电机驱动控制系统在运行过程中的各项参数通过CAN协议与基于LabVIEW的上位机进行通讯。仿真实验结果表明,与传统指数趋近律以及PI控制器相比,该控制系统电机的相电流品质和转矩抖动得到明显的改善,同时提高了系统的鲁棒性。In order to reduce the torque ripple of the permanent magnet synchronous motor(PMSM),improve the ability of the system to adjust the speed adaptively,thereby reducing the system energy consumption and improving the endurance of the new energy electric vehicle,a new sliding mode approach law was designed.The control system under the new reaching law was compared with the traditional sliding mode control system and PI control system.The new sliding mode control algorithm was verified on the hardware circuit based on DSP chip TMS320F28335.The parameters of the motor drive control system during operation were communicated with the host computer based on LabVIEW through the CAN protocol.The simulation results show that compared with the traditional exponential approach law and PI controller,the phase current quality and torque jitter of the designed control system motor were significantly improved,and the robustness of the system was improved.
