摘　　要：针对受到扰动的变机翼后掠角近空间飞行器,研究一类基于多模型切换的多输入多输出非线性系统的模糊自适应鲁棒控制器的设计问题.通过构造公共Lyapunov函数设计系统的控制器,采用动态面控制方法避免了控制器设计中的计算膨胀问题,利用自适应模糊系统和鲁棒控制项在线消除系统中的未知干扰影响.仿真结果表明了该方法的有效性.According to the near space vehicle with disturbances, whOse wing sweep angle is variable, the problem of designing a fuzzy adaptive controller is considered for multi-input and multi-output nonlinear systems based on multiple models switching. The common Lyapunov function and the controller are simultaneously designed. The dynamic surface control approach is used to avoid the problem of the explosion of calculation. The adaptive fuzzy systems and the robust controllers are adopted to eliminate the influence of the unknown disturbances on line. Simulation results show the effectiveness of the proposed method.
