基于模糊自适应PID控制的弹药纵向回路设计

Ammunition longitudinal circuit design based on fuzzy adaptive PID control

根据灵巧型弹药的特点,本文提出了在普通弹药中加入模糊自适应PID控制器。首先根据弹药数学模型设计了弹药纵向控制回路,然后依据专家经验得出误差与误差变化率和控制器参数的模糊规律,最后通过Matlab进行了数字仿真。仿真结果表明相比普通数字PID控制器,模糊自适应PID能使系统更快的稳定,且无超调,鲁棒性强。

According to the characteristics of smart ammunitions, this paper proposes to join the fuzzy adaptive PID controller in the general ammunition. First, ammunition longitudinal control loop was designed according to ammunition mathematical model, and then on the basis of expect experience, the error and error change rate and fuzzy rules of the controller parameters were obtained. Finally simulation was carry out. The simulation results show that compared with ordinary digital PID controller, fuzzy adaptive PID can make the system stable quickly without overshoot, and robustness is strong.
