摘　　要：针对实际系统运行过程中所存在的转动惯量和负载力矩变化大等各种不确定因素,设计了一种基于动态面滤波法的自适应鲁棒位置控制器(ADSC)。首先对于模型中的不确定参数,采用投影算法进行有效估计,利用动态面滤波器简化控制器的设计,通过对模型的等价变换和选择适当的Lyapunov函数,最终给出系统的自适应控制器设计方法。仿真和实验结果表明,该方案与自适应反步滑模控制(ABSMC)相比,该控制器能够有效抑制抖振,跟踪性能好,对参数摄动及外界负载扰动具有较强的鲁棒性。Aiming at wide variations in moment of inertia,large disturbed moment of a rocket launcher position servo system, a adaptive robust controller based on dynamic filtering method （ADSC） was presented. A projection-type estimation algorithm was adopted to tackle model uncertainties,and design of the controller was Simplified by using a dynamic filter,and model uncertainties were compensated by combining a simple robust backstepping method. Besides,the controller and adaptation laws for uncertain parameters were presented by selecting both the equivalent model transformation and a proper Lyapunov function. The simulation and experimentation results show that the proposed approach can eliminate chattering problem effectively,guarantee control accuracy,and possess a strong robustness to both parameter perturbation and load disturbance to the adaptive backstepping Sliding Mode Controller （ABSMC）.
