摘要
针对机载布撒器俯仰通道,提出一种设计多胞变增益混合H2/H∞输出反馈控制器的新方法。通过引入滤波器,得到易于利用多胞技术设计变增益控制器的俯仰通道增广对象,将其凸分解为多胞表示。利用多胞特性将整个控制器的设计转化为对胞体顶点控制器的设计,利用LMI方法对各顶点分别设计满足混合H2/H∞性能指标的输出反馈控制器,综合各顶点控制器得到具有多胞结构的全局变增益控制器。仿真结果验证了该控制器具有良好的性能。
A new approach to design polytopic gain scheduled mixed H2/H∞ output feedback controllers for airborne dispenser pitch channel is presented. A filter is introduced to obtain a pitch channel augmented system, which is apt to have the polytopic gain scheduled controller designed. Then the system is put into a polytopic expression by a convex decomposition. The polytopic features are used to simplify the controller design to be a vertices＇ controller design for the polytope. An output feedback controller, which satisfies satisfies H2/H∞performance, for each vertex of the polytope is designed with a LMI approach. A global gain scheduled controller is obtained by a synthesis of the vertex controllers. Simulation results demonstrate that the controller has favorable performance
