【摘要】：永磁同步电机因为具有功率密度高,调速范围宽的特点被广泛应用于电动汽车驱动电机。由于调速范围宽,启动性能好的原因,永磁同步电机控制策略一般选择矢量控制策略。结合电动汽车驱动电机的应用环境,无机械式传感器矢量控制拥有深刻的研究意义。本文首先对电动汽车驱动电机控制策略结合电动汽车应用环境作比较分析,阐述无机械式传感器控制在电动汽车驱动电机控制策略的研究意义。研究永磁同步电机的结构与原理,对永磁同步电机进行数学建模,并阐述了矢量控制策略的原理。针对电机驱动介绍了空间矢量脉冲宽度调制。其次针对永磁同步电机矢量控制,基于永磁同步电机在旋转坐标系下的数学模型,根据滑模变结构控制原理,设计了一种双滑模结构无机械式传感器矢量控制。基于MATLAB Simlink仿真环境对设计的双滑模结构矢量控制策略进行建模仿真,仿真结果验证了所设计控制策略的可行性。然后基于智能功率模块PS21869与数字信号处理器TMS320F2812,设计永磁同步电机控制系统实验平台。基于CCS3.3开发环境为永磁同步电机控制系统设计控制程序,并运用虚拟仪器技术为控制系统设计了实验检测软件。最后利用设计的控制系统实验平台进行永磁同步电机控制实验,实验结果与仿真结果相符合。
[Abstract]:Permanent magnet synchronous motor (PMSM) is widely used in electric motor drive motor because of its high power density and wide range of speed regulation. Because of the wide speed range and good starting performance, permanent magnet synchronous motor control strategy generally chooses vector control strategy. It combines with the application environment of electric vehicle driving machine, and no mechanical sensor vectorial control is used. The system has profound research significance. Firstly, this paper makes a comparative analysis of the control strategy of electric motor drive motor and the application environment of electric vehicle, and expounds the significance of the research on the control strategy of the non mechanical sensor control in the driving motor of the electric vehicle. The principle of vector control strategy is introduced. Space vector pulse width modulation is introduced for motor drive. Secondly, based on the vector control of permanent magnet synchronous motor, based on the mathematical model of PMSM in rotating coordinate system, a double sliding mode structure without mechanical sensor vector control is designed according to the sliding mode variable structure control principle. Based on the MATLAB Simlink simulation environment, the design of the dual sliding mode structure vector control strategy is modeled and simulated, and the simulation results verify the feasibility of the designed control strategy. Then based on the intelligent power module PS21869 and the digital signal processor TMS320F2812, the experimental platform of the permanent magnet synchronous motor control system is designed. Based on the CCS3.3 development environment, the control system is designed. The control program for permanent magnet synchronous motor control system is designed and the experimental testing software is designed for the control system using virtual instrument technology. Finally, the control experiment of permanent magnet synchronous motor is carried out by the designed control system experimental platform. The experimental results agree with the simulation results.
