摘　　要：红外成像导引头是精确制导导弹系统的重要组成部分,导引头随动控制系统的性能决定着导弹的跟踪精度水平。为了提高其控制系统的动态性能和跟踪精度,设计了一种比例因子自校正模糊PID控制器并引入到导引头控制回路中。结果表明,与传统PID控制器相比,模糊PID控制器明显提高系统的动、静态指标,同时系统具有较强的适应性和鲁棒性。Infrared imaging seeker is considered as one of the most important parts of the precision- guided missile, while the performance of the seeker control system is a vital prerequisite to improve the tracking accuracy. In order to improve the performance of system, a scale factor self-correction fuzzy pro- portional integral derivative （PID） controller is designed and introduced into the seeker control loop. The simulation results show that the fuzzy control system can improve the dynamic and static performance and strengthen the robustness and suitability of the system, compared to the traditional PID.
