Observer-based robust fuzzy control of nonlinear systems with parametric uncertainties

对一类非线性系统进行模糊建模及其模糊观测器设计 ,研究了在系统的状态不可测且存在参数不确定的模糊鲁棒控制问题 ,以线性矩阵不等式的形式给出了模糊控制系统具有李雅普诺夫意义下稳定的充分条件 ,最后把所提出的方法应用到倒立摆系统进行仿真 ,仿真结果验证了该控制方法的有效性 .

This paper addresses the robust fuzzy control problem for nonlinear systems in the presence of parametric uncertainties and the state variables unavailable for measurement. Sufficient conditions are derived for robust stabilization in the sense of Lyapunov asymptotic stability and are formulated in the format of linear matrix inequalities (LMIs). The effectiveness of the proposed fuzzy controller and fuzzy observer design methodology is finally demonstrated through numerical simulations on an inverted pendulum system.
