To stabilize and improve the performance of tracking platform for the problem of the existing literature focused on the theoretical study, the prototype of airborne four-frame stability and tracking platform is established. The prototype of airborne four-frame stability and tracking platform for the study, the mechanical system and electrical control system are described, the servo control loop and automatic tracking control loop are designed, and the corresponding control strategy is provided. The results show that the design theory analysis is correct, the control system is reasonable.
