| Abstract: | Focused on the 500 m aperture spherical radio telescope (FAST) project needs, this paper reviews a new type of hydraulic actuator, describes its working principle and the functions of the hydraulic actuator while it is used in the active reflector system. Furthermore, experiments on the actuator are carried out to evaluate the effectiveness in changing the target source state and scanning tracking state. The results show that the dynamic performance and the control accuracy of the hydraulic actuator can meet the engineering requirements of the FAST project, which means it has good practicality. |
