摘　　要：基于动态逆方法及鲁棒轨迹跟踪控制理论提出了一种新的导弹控制系统设计方法。首先基于导弹的非线性模型设计快、较慢回路的动态逆控制器以实现其非线性解耦,然后在较慢回路中设计鲁棒控制律以补偿整个控制系统的总不确定性及干扰。即对较慢回路进行动态逆控制的基础上,通过引入一种辅助控制输入信号以抵消不确定性及外部干扰对系统性能的影响。稳定性分析表明了闭环系统稳定且系统跟踪误差能满足给定的性能指标。最后通过对所设计控制系统的仿真分析,验证了该方法的有效性。A novel missile control system design approach based on dynamic inverse and robust trajectory tracking control in presented in this paper.Firstly,dynamic inversion controllers are designed in both fast loop and relatively slow loop for decoupling control.Secondly,robust control law is designed in relatively slow loop to compensate uncertainties and disturbances of the whole system.The effects of uncertainties and disturbances on the control system performance are cancelled by introducing a subsidiary control signal on the basis of dynamic inverse control law designed for the slow loop.Stability analysis demonstrates that the controller can guarantee the stability of the overall system and attenuate tracking errors to a prescribed level.Finally,the simulation result shows the effectiveness of the control method.
