Abstract

To meet the high requirements of missile rudder control, this paper offer the design of digital servo control system with digital PWM technology. Meanwhile, the structure and control schemes of system are analyzed and the design of software and hardware is explained in the paper. The system with permanent magnet DC motor as servo motor is based on Microchip DsPIC30F5011. The control strategy combining Mixed Fuzzy-PID and traditional PID may serve as primary control algorithm of system. The experimental results show that this control system with the property of high accuracy and realtime capability is efficient and stable, and is more suitable for a type of high speed missile rudder control system.
