According to the requirement of miniaturized phased array antenna TT&C system, a design method of servo control system for phased array antenna turntable is presented, which adopts the integrated design idea. The servo control system is integrated in the turntable. The system with a beam controller includes the function of controlling the antenna beam and automatically tracking the target, the remote control of multiple servo control systems can be realized through network communication. The servo controller of servo control system adopts the compound control algorithm of the parameter self-turning fuzzy PID algorithm and time optimal algorithm. The results of step signal, sinusoidal signal and tracking test indicate that the servo control system has excellent dynamic performance and high tracking precision. This servo control system has rich functions, good control performance and broad application prospects.
