摘要 设计的电动助力转向表面式永磁同步电机变频调速系统由永磁同步电机、逆变器、转子位置检测装置和控制单元构成。表面式永磁同步电机电动助力转向系统的控制包括扭矩控制和矢量控制。扭矩控制是表面式永磁同步电机电动助力转向系统控制目标,矢量控制是对表面式永磁同步电机定子电流矢量的控制。阐明了表面式永磁同步电机电动助力转向系统的控制过程,分析了表面式永磁同步电机电动助力转向控制系统的助力特性设置、坐标变换和脉宽调制技术。 The variable frequency speed regulation system of EPS (electric power steering) surface PMSM (permanent magnetic synchronous motor) is made up of the PMSM. the inverter, the rotor position sensor and the control unit. The control of surface PMSM electric power steering system includes the torque control and the vector control. The torque control is the control target of the surface PMSM electric power steering system. And the vector control is the control of stator current vector of the surface PMSM. The control process of the surface PMSM electric power steering system is illustrated. The setting of the assist characteristic, the coordinate transformations and the PWM technologies of the control system of the surface PMSM electric power steering are analyzed.
