Simulation Research for Servo System of Antiaircraft Based on SVPWM Technique

Different drive modes of servo system are analysed on their merits and disadvantages in allusion to the characteristics of small caliber antiaircraft gun system. The use of Permanent Magnet Synchronous Motor (PMSM)with Space Vector Pulse Width Modulation (SVPWM)in small caliber antiaircraft gun servo is discussed. Modelling and simulation research of dynamic control process for certain small caliber antiaircraft gun servo with SVPWM control are achieved with Simulink. The results show that,servo system with SVPWM control not only takes on small structure and light weight, but also achieves high speed response and accurate control precision,which meets the requirements of tactical and technology indexes.
