A robust active control based on minimum sensitivity

本文建立了带有参数摄动的结构状态空间模型。在此基础上 ,提出了基于参数灵敏度最小的鲁棒极点配置的主动控制算法 ,通过使闭环系统的特征值对系统参数变化不敏感来提高结构控制系统对参数摄动的鲁棒性。最后对一个单自由度结构地震作用下的控制仿真计算 。

A state space model with parameter perturbations of structure system is established in this paper. Moreover, a robust pole assignment algorithm with minimum sensitivity is presented, which gives a robust solution in the sense that the closed loop eigenvalues are as insensitive as possible to the variations of system parameters . Finally, a SDOF building model under earthquake excitation is analyzed using this method. The simulation results show that the presented method is effective and robust.
