This paper addressed the design of the servo - control part of the control system in detail . we use hydraulic actuator and displacement sensor to set up a hydrauservo system ; we also use the hydraulic lock and embedded controller to make it safety 本文详述了地面操纵系统中液压伺服控制部份的设计：通过采用液压作动筒+位移传感器的方案来实现位置伺服控制；通过采用液压锁+嵌入式控制器的方案来保证系统的安全。
