Controller Design and Stability Analysis of Time-Continuous Systems Based on a Fuzzy State Model
-
摘要: 首先给出连续系统模糊状态模型的表示方法,在此基础上给出了一种模糊状态反 馈控制器的设计方法,对其稳定性进行了分析,得出了一个确保系统全局稳定的充分条件. 同时也提出一种模糊观测器的设计方法,并对其收敛性进行分析,得出了确保收敛的一个充 分条件.Abstract: A fuzzy state model for time-continuous systems is presented. Based on the mod- el a controller design method with fuzzy state feedback is given. The stability of the fuzzy systems is analyzed. A design method for fuzzy observers is aslo given. A sufficient condition which guarantees the convergence of the estimated states to the real states is obtained.
