摘要:

针对随动定向战斗部随动系统工作中存在的非线性与随机干扰问题,普通的PID控制器和模糊控制器不能满足快速性与适应性的要求,基于模糊自整定PID参数控制器与模糊-PID切换控制器,提出了一种新型模糊-PID复合控制算法,控制前段利用模糊控制加快控制速度,后段利用模糊逻辑整定PID参数提高精度与自适应能力;仿真结果表明,采用这种新型模糊-PID复合控制算法能够保持跟踪精度,减少调节时间,加快系统跟踪速度,减小切换冲击,提高抗干扰能力。

Abstract:

The conventional PID controller and Fuzzy controller can not fulfill the requirement of speediness and adaptability for servo aimable warhead servo system due to nonlinear problem and random disturbances.Therefore, we proposed a new type of Fuzzy-PID composite controller based on Fuzzy self-tuning PID controller and Fuzzy-PID switching controller, the front to speed up the control with fuzzy control, and then setting the PID parameter by fuzzy logic to improve precision and adaptive ability. Simulation demonstrated that the new type of Fuzzy-PID composite control algorithm can keep high tracking precision, reduce the adjustment time and switching impact while improve the tracking speed and robustness.
