摘　　要：坦克炮控系统内部存在摩擦、齿隙和参数漂移等多种非线性,严重影响了系统性能的发挥。基于"等效扰动"的思想,将系统的各种非线性环节等效为外部扰动,从而将复杂的非线性系统转化为带可测扰动的线性系统。在此基础上设计了基于扩张状态观测器的自适应模型跟随控制器,实现了炮控系统多种非线性的补偿控制,实验表明,这种控制方法能够有效地抑制非线性扰动的影响,改善系统性能,且易于工程实现。There are diversified nonlinearity such as backlash, friction and varieties of system parameters in tank gun control system; they badly influence the system performance exertion. Based on the thought of ＇equivalent disturbance＇, the nonlinearity are equal to exterior disturbance; consequently the nonlinear system is translated into the linear system included disturbance. What is more, the adaptive model following controller based on ESO is designed, and the compensation control of nonlinearity Js implemented. The result shows that the influences caused by the diversified nonlinearity are restrained and the system performance is improved soundly by the method which is easy to be carried out in engineering project.
