中文摘要

      本文提出这一种基于观测器的低灵敏度调节器，证明了状态灵敏度观测器的充要条件。将重构的状态灵敏度向量引入二次积分指标中，导出了低灵敏度调节器的设计方法。仿真结果表明，按该方法设计的控制系统的响应对参数摄动不敏感，即控制系统具有较强的鲁棒性，此外，该方法还具有计算量小，容易实现的优点。

英文摘要

      An observer-based sensitivity-reduced regulators is presented in this paper. The theorems on sufficient and necessary conditions of the observer of state sensitivity are given and proven. The design method of sensitivity-reduced regulators is resulted from introducing reconstructed state sensitivity vectors into the quadratic integration cost. Simulation results showed that the response of the closed-loop control system is not susceptible to parametric perturbation. In addition, the design of regulator need less computation amount than the previous methods.
