摘　　要：新能源汽车所用永磁同步电机(PMSM)面向复杂的路面条件和操作工况时,对其转矩控制实时性要求高,具有较大的操作难度。因此提出了一种基于泛布尔代数的车用永磁同步电机控制器,该控制器将永磁同步电机的运行状况分为25个区域,并在不同的区域应用相应的控制作用。该控制算法结构简单,逻辑概念直观,容易实现。仿真结果表明,采用该控制器的空间矢量调制直接转矩控制(SVM-DTC)系统调节速度快,低超调量,调节精度高。The Permanent Magnet Synchronous Motor(PMSM)for new energy vehicles works in complex road conditions and operating environment.Its torque control is very difficult since it requires good real-time performance.A PMSM controller based on Pan-Boolean algebra for electric vehicle is proposed.The controller divides the operating condition of PMSM into 25 regions and applies corresponding control function in different regions.The control algorithm has simple structure,intuitive logic concepts and is easy to implement.The simulation results show that the SVM-DTC control system with this controller has the advantages of fast regulation speed,low overshoot and high precision.
