基于自适应模糊滑模的复合控制导弹制导控制一体化反演设计

针对姿控式直接力/气动力复合控制导弹，提出一种基于滑模反演控制的制导控制一体化控制律。通过引入指令滤波器，避免了传统反演设计存在的计算膨胀问题；设计自适应模糊逼近器对系统不确定函数进行逼近，并构造误差滑模面来补偿模糊逼近误差及有界干扰对系统的影响，通过在线自适应调整控制律参数实现系统的鲁棒性。具体的数值算例仿真计算表明：在目标机动的情况下，所设计的一体化制导控制系统具有较强的抗干扰能力，在保证系统稳定的同时可达到满意的制导控制效果。

Integrated Guidance and Control Backstepping Design of Blended Control Missile Based on Adaptive Fuzzy Sliding Mode Control

An integrated guidance and control law is proposed for dual-control missiles based on the backstepping sliding mode design approach. A command filter is introduced to eliminate the computation explosion problem of conventional backstepping design method. An adaptive fuzzy approximator is employed to approximate the system uncertain functions, and a sliding mode surface is constructed to compensate the effects of approximate error and bounded disturbances. The controller parameters are adjusted adaptively on-line to guarantee the robustness of the system. A numerical example is provided. The simulation results show that the integrated guidance and control approach has robustness to disturbances and improves the control performance while ensuring the operating stability of system when a target maneuvers with high acceleration.
