摘　　要：将脉宽调制变频调速技术应用于电动执行机构的电机控制。简要介绍了所采用的控制芯片和功率模块,阐述了相应的变频调速原理。设计出基于INTEL专用电机控制单片机196MC的变频调速装置。根据电动执行机构的特点,对电机在各种运行状态下的控制算法做了详细介绍。实际运行表明,采用变频调速控制的电动执行机构的性能大大优于一般的执行机构。The PWM frequency conversion method is used for motor control of the electric actuator. First the chips which are used for hardware design are briefly introduced, also the control system structure. Then the VVVF principle of the 196MC is explained. Based on the characteristics of electric actuator, it expatiates on the arithmetics used in various operation states. The running state at the working field indicates that the performance of electric actuator with VVVF AC drive is superior to the general one.
