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