Abstract： In order to accurately and promptly adjust the fan stator blade angle， a stator blade adjustment actuator based on electro-hydraulic control technology is designed. First， the hydraulic system of the stationary blade adjusting actuator is introduced， and then the hardware structure and software programming points of the PLC control system are introduced. By adding the weight of the integral term， the defects of the classic PID control method are improved and the response speed and stability of the system are improved.
