摘要
研究了一种混合H_2/H_∞变增益状态反馈控制方法。在矩阵多胞域内,给出了只依赖于多胞顶点且使闭环系统稳定及满足预定的H_2和H_∞性能的线性矩阵不等式条件,并得到了对应的控制器。该方法不受对象结构约束,且适用于参数快变系统。将该方法应用于机载布撒器俯仰通道自动驾驶仪设计,结果显示了控制器的有效性。
A mixed H2/H∞ gain scheduled state feedback control method is investigated. In a polytopic domain, linear matrix inequality conditions that depend only on the vertices of polytope are presented to make sure that the prescribed H2 attenuation level, H∞ attenuation level and the stability of the closed system are guaranteed. And the solution of the controller is therefore obtained. This method is not constrained by target structure and can be used in rapidly-changing parameter system. When the method is applied to the design of an airborne dispenser pitch axis, the result proves the effectiveness of the proposed controller.
