摘　　要：防空火箭炮交流伺服系统作为一个非线性动力学系统,在一定参数范围和外部输入下可以呈现非常复杂的混沌运动或极限环,其混沌特性较为显著.在防空火箭炮交流伺服系统非线性数学模型的基础上,分析了系统平衡点性质,证明了系统Hopf分岔的存在,并给出了有关的分岔图、Lyapunov指数谱和相平面图.进一步设计了一种自适应状态反馈控制器,当系统在一定参数下呈现混沌运动时,可以将混沌运动控制到期望的稳定状态,数值仿真表明了该控制方法的有效性.The AC servo system of air-defense rocket launcher, which is a nonlinear dynamicsystem, can exhibit a variety of chaotic or limit-cycle phenomenon under some choices of systemparameters and external inputs, and its chaotic characteristics are more prominent. Based on themathematical model of the air-defense rocket launcher AC servo system, the property ofequilibrium points was analyzed and the existence of Hopf bifurcation was proved. In addition,bifurcation diagram, Lyapunov exponent map and phase plane diagram were also given in thispaper. An adaptive state-feedback controller was designed to control the chaotic movement toreach a stable status under certain system parameters. Numerical simulation proves the validityof this control method.
