| Abstract: | 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. |
