- 摘要针对直流电机脉宽调制控制系统的工作原理，分析了受限单极和双极脉宽调制控制模式应用于电动助力转向系统电机驱动时的优缺点，提出了一种“半双极”控制模式及该模式下占空比的修正方法。
Based on the working principle of pulse width modulation (PWM) control system for DC motor, the strong and weak points of two conventional PWM control modes (limited single polar mode and bipolar mode), when used in electric power steering (EPS) system are analyzed, and a new PWM control, so called quasi-bipolar control mode is proposed with the correction method of its duly ratio given.
