防空武器站模糊自适应滑模位置控制设计方法

针对特种防空武器站伺服系统负载变化范围大、发射扰动力矩强和跟踪精度要求高等特点，提出了一种模糊调节的伺服系统滑模位置控制器设计方法. 采用滑模控制抑制参数摄动及外界干扰，采用模糊规则调节滑模趋近速度并削弱滑模抖振. 仿真和实验结果表明，该控制策略不仅保证了系统的响应速度和动态精度，而且对负载扰动和系统参数摄动具有较强的鲁棒性. 

Design of Fuzzy Adaptive Sliding Mode Controller for Air Defense Weapon Station

Considering the characteristics of air defense weapon station ac servo system including large change range of load, intense disturbance torque when launching and high requirement for tracking accuracy, a position controller based on fuzzy adaptive sliding mode was designed. Sliding mode control can restrain influences of parameter uncertainties and external disturbance while fuzzy rules can adjust reaching speed adaptively and reduce chattering of sliding mode control. Simulation analysis and experimental results show that the proposed approach can guarantee the static and dynamic characteristics and the system possesses strong robustness against load disturbance and parameter perturbation. The results can provide a reference for practical application of advanced intelligent algorithms.
