挠性航天器控制系统的最优综合

THE OPTIMAL SYNTHESIS OF FLEXIBLE SPACECRAFT CONTROL SYSTEMS

本文研究了挠性航天器控制系统的最优综合设计问题，给出了系统最优时控制律和执行机构与传感器配置应满足的非线性方程，而且在这一设计过程中通过使用特征值灵敏度约束，明显降低了控制系统对执行机构和传感器安装误差的敏感性，克服了轨迹敏感性约束和单纯使用特征值灵敏度指标的不足。

In this paper,the optimal Synthetic design problem of flexible spacecraft Contral Systems is Studied. The nonlinear equations of determining the optimal solution of control law and allocation of actuators and sensors are presented,and a constraint of closed loop eigenvalue sensitivity is introduced to improve sensitivity robustness. The conclusion shows that the method is useful in synthetic design with improving sensitivity robustness.
