摘　　要：现代战争对车载防空武器的低空高速目标的快速跟踪能力提出了很高的要求;为实现某车载发射转塔随动系统的高速高精度控制任务,抑制系统中齿隙引起的极限环振荡,提出了一种将智能分区PID反馈控制与前馈控制相结合的位置随动控制策略,并给出了易于工程实现的PID参数调整规则;设计了以嵌入式计算机PC104为核心的车载发射转塔数字交流随动系统;应用机理分析与实验相结合的方法建立了该系统的数学模型;系统仿真和实际控制结果表明,采用本文所提控制策略,可有效解决随动系统设计中快速性和稳态精度的矛盾,使系统在获得良好动、静态性能的同时,避免了极限环振荡;该方法具有较好的实用性。For the requirements of modern war, the car--borne aerial defendable weapons need be of fast following ability to low--level targets with high speed. In order to realize the control tasks with high speed and high precision, as well as to restrain the oscillation of limit ring caused by backlash, a control strategy combining with intelligent subarea PID control and feedforward control is proposed for the position servo system. And the parameters tuning rules for the subarea PID are given which are easily realized in engineering. A digital AC servo system of a car-- borne launch turret based on embedded computer PC104 is designed. The servo system is modeled with a synthesis method combined by mechanical analysis and experi ments. The simulation results and experiment results show that by applying the proposed control strategy the contradictions between dynamic and steady performances in the servo system can be solved effectively. The performance with high stability, high speed and high precision had been ob tained. Also the oscillation of the limit ring had been eliminated.
