摘　　要：为提升末端反导舰炮的射击精度,提出一种舰炮随动系统的模糊滑模控制方法。采用LuGre模型对末端反导舰炮随动系统中的非线性摩擦进行建模,应用滑模控制算法对摩擦力矩进行补偿,通过模糊规则对滑模控制增益进行调节以降低抖振。仿真结果表明:该模糊滑模控制器减小了控制输入的抖振,提高了随动系统跟踪稳定性和跟踪精度。In order to improve the firing accuracy of the terminal anti-missile naval gun,a fuzzy sliding mode control method for servo system is proposed.Using LuGre model,the nonlinear friction in naval gun servo system model is established.The sliding mode control algorithm is used to compensate the friction torque,and the fuzzy rules are used to adjust the sliding mode control gain to reduce chattering.The simulation results show that the fuzzy sliding mode controller reduces the chattering of the control input and improves the tracking stability and accuracy of the naval gun servo system.
