积分模糊变结构控制的导弹侧向自动驾驶仪设计

针对导弹侧向稳定回路这一参数大范围快时变系统,应用一种积分模糊滑模控制方法来设计自动驾驶仪.通过模糊控制和滑模控制的有机结合,并引入积分环节,使得控制输出得到连续化,避免了变结构控制所固有高频颤振现象,易于工程实现.仿真结果表明,给出的积分模糊变结构控制器,能够抑制弹体模型参数的大范围变化和外界干扰等不确定因素的作用,具有很强的鲁棒性和良好的动态性能.

Integral Fuzzy Sliding Mode Control for Missile Autopilot Design

This paper applies the method of integral fuzzy sliding mode control to design missile's autopilot,which incorporates sliding mode control with the fuzzy control and introduces an integral control into the controller.This method linearizes the control output and completely avoids the chattering phenomenon in sliding mode control.The simulation results show,this control method can restrain the effect of model parameter variation and external disturbances,and exhibits strong robustness and excellent dynamic c...
