摘　　要：结构摄动系统具有模态解耦的极点配置问题,对航空航天、动态电压调节等控制系统等均有十分重要的现实意义。针对开环系统部分参数摄动设计闭环特征值灵敏度指标,经参数化特征向量,将具有模态解耦鲁棒状态反馈极点配置问题转化为带有解耦约束条件的优化问题,通过推导梯度公式,确定设计参数,同时实现了解耦控制和极点配置,并设计了算法和算例,说明算法简单、有效。The Structural perturbation system with pole assignment of modal decoupling has very important practical significance to aerospace, dynamic voltage regulation control system. The sensitivity index of closed-loop eigenvalue is designed according to the features of open loop system parameter perturbation, and the assignment problem of modal decoupling robust state feedback pole is transformed into the optimization problem of decoupling constraint through parameterized feature vector. The design parameters are confirmed by educing gradient formula, meanwhile,decoupling control and pole assignment are realized and the algorithm anti numeral example are designecl. The results prove that the algorithm is simple and effective.
