摘要
由于载机的振动和机动、被控对象参数的摄动、非线性环节等,经典PID控制算法无法满足机载激光武器跟瞄系统对目标的跟踪精度要求。在复合轴跟踪瞄准控制结构的基础上,设计了具有自适应能力的模糊PID控制器,构建了Matlab/Simulink仿真模型。仿真结果表明,模糊自适应PID控制器跟踪阶跃信号的超调量仅为经典PID控制器的0.23倍,能较好的改善机载激光武器系统的跟踪性能。
Because of carrier aircraft vibration and motor, controlled object parameter changes and non-linear element and so on, classical PID control algorithm can not meet the accuracy requirement of the tracking and pointing system of the airborne laser weapon. Based on the compound-axis control structure of the tracking and pointing system, the fuzzy self-adaptive PID controller is designed, and the Matlab/ Simulink simulation model is built. Simulation results show that the overshoot of tracking step signal of the fuzzy self-adaptive PID controller is only 0.23 times that of the classical PID controller, the fuzzy self-adaptive PID controller can effectively adjust the tracking capability of the airborne laser weapon.
