The basic principle of the aiming device and its servo control system were introduced, and the system design scheme was put forward and researched by use of torque motor direct drive, the revolver feedback, the TMS320F28335 digital signal control, and power drive of PWM. The incremental PID control strategy were used to get the higher accuracy and the better stability for tracking target with the aid of the current loop, velocity loop and position loop. And the hardware circuit, control method and software procedure were analyzed in detail. The system made use of abundant source of TMS320F28335 and CPL＇s strong logic ability to greatly simplify system structure. The experiments showed that the system has stronger ability in tracking precision and excellent dynamic performance, the system working index can perfectly meet the requirements.
