摘　　要：针对坦克炮控系统这一类非线性和不确定性的复杂对象控制问题,提出一种自适应模糊滑模控制方法。采用滑模控制与模糊逻辑相结合的方法,滑模开关函数的绝对值作为输入组成一维模糊逻辑推理器,它的输出用以在线调整一维模糊控制器的输出增益,依据Lyapunov稳定定理获得最终的控制量。系统中的滑模控制器保证了系统的快速跟踪性能;而模糊控制器抑制了闭环系统的各种扰动,在不牺牲系统鲁棒性的同时达到削弱抖振的目的。从理论上证明了系统的稳定性,并且通过仿真验证了该结果。仿真结果表明,该设计方法大大优于经典设计,而且结构简单,易于设计,为炮控系统实际设计提供了一种可行的方法。A new method of adaptive fuzzy-sliding mode control for tank gun control system that contains nonlinearity and uncertainty is presented. The method that the sliding mode control and the fuzzy logic were integrated is adopted. Absolute value of sliding mode on-off function as input composes one-dimension fuzzy logic interference and its output adjusts online output gain of one dimension fuzzy logic controller, Using Lyapunov law, we can get the sliding-mode control variable. The sliding mode tracking controller is designed to ensure that the system has fast tracking characteristic, and the fuzzy controller can suppress the disturbances within the close loop and reduce the chattering with good robusmess of system. The paper theorefically proves the asymptotic stability of the system, and the simulation results are valid. Simulation resuits show that this is more excel than classical design, its structure is simple and is designed easily, and thus a new realistic technique is provided for the design of gun control system of tank.
