摘　　要：设计了一种有效驱动EPS助力电机的电路与程序。设计了MOSFET前置驱动电路来保证逆变电路的正常工作,并通过逆变电路将直流电源转换成三相交流电来驱动助力电机PMSM;通过实时采集电机相电流大小、转子的位置信号,应用PID闭环控制方法,实现了助力电机PMSM的磁场定向控制。实验验证表明:设计的驱动电路与程序能够有效驱动助力电机。The circuit and program whiCh can drive EPS motor effectively were designed. MOFET pre-drive circuit was designed to ensure the normal work of the inverter circuit, and DC power was converted to three-phase alternating current to drive the motor PMSM through the inverter circuit： Through real-time collection of motor phase current and rotor position signal, and application of PII3 closed loop control methbd, the field oriented control of the motor PMSM was realized. The experi： mental verification shows the drive circuit and program designed cfih drive motor effectively.
