摘　　要：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。An integrated guidance and control law is proposed for dual-control missiles based on the back- stepping sliding mode design approach. A command filter is introduced to eliminate the computation ex- plosion 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 adap- tively 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 im- proves the control performance while ensuring the operating stability of system when a target maneuvers with high acceleration.
