【摘要】 小口径高炮随动系统的特点是体积小、重量轻,要求反应迅速、控制精度高,采用交流驱动模式及直流驱动模式各有其优缺点,分析了基于SVPWM控制技术的永磁交流同步电机(PMSM)在小口径高炮随动系统中的应用。利用Simulink仿真语言,构建某型小口径高炮随动系统SVPWM控制技术仿真模型,对其控制过程进行仿真分析。仿真结果表明,采用SVPWM控制技术,在小口径高炮随动系统结构趋于小型化、重量减轻、体积缩小的前提下,响应速度快、控制精度高,能够满足战技指标要求。更多还原

【Abstract】 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.更多还原
