摘　　要：坦克炮控伺服系统存在低速摩擦,摩擦环节不但造成系统的稳态误差,而且导致极限环振荡、低速爬行等现象。提出基于Lyapunov稳定理论的滑模控制方法,通过Lyapunov稳定理论获得控制量,同时克服参数不确定性和补偿非线性摩擦力矩,从而保证跟踪误差渐进收敛。仿真结果表明该设计方法大大优于经典设计,为炮控伺服系统实际设计提供了一种可行的新方法。Gun control servo system of tank exists low speed friction, and the friction not only works system steady-state error, but also makes limit cycle oscillation and static-slip phenomena are induced by nonlinear friction. A slide mode control design is presented based Lyapunov steady method, and gain control magnitude by Lyapunov steady method, it overcomes parameter uncertain behavior and compensates nonlinear friction, so ensures tracking error asymptotically converge. Simulation results show this is more excelled than classical design, and thus a realistic new technique is provided for the design of gun control servo system of tank.
