摘　　要：为提高轻武器伺服跟踪系统的动态性能,提出一种模糊PID变阻尼控制方法.该方法利用模糊PID控制技术在线调整速度反馈通道增益以改变系统的阻尼比,从而达到改善系统动态性能的目的.仿真试验表明,采用模糊PID变阻尼控制方法能明显克服武器搭载云台运动过程中产生的过冲和抖动现象,满足伺服跟踪系统的实时性、准确性和稳定性要求.To improve dynamic tracking performance of the servo tracking system mounted with a small arm,a variable damping ratio control algorithm by fuzzy PID is proposed.Fuzzy PID control technique is employed to vary damping ratios of the system by adjusting feedback gains of velocity loop online,which consequently improve the system＇s dynamic performance.Simulation results indicated that variable damping ratio control algorithm by fuzzy PID is able to resolve overshoot and oscillation of the servo tracking system mounted with a small arm,and the system can work prospectively.
