【摘要】 采用模糊T-S模型描述一类匹配不确定的非线性系统,结合滑模观测器设计原理,提出基于T-S模糊模型的鲁棒模糊滑模观测器设计方法。采用Lyapunov函数作为稳定模糊观测器的判别条件,使设计的观测器一致收敛,状态估计达到预期的指标;运用LMI和区域极点配置方法,设计鲁棒模糊滑模观测器的综合算法;将该设计方法应用于倒立摆的平衡控制系统进行相应的数字仿真,验证其可行性。更多还原

【Abstract】 A class of the matched uncertain nonlinear systems was described by the Takagi-Sugeno(T-S) fuzzy dynamic model,and a new method of designing the robust fuzzy sliding mode observer based on T-S fuzzy model was proposed by applying the sliding-mode observer design principle.The Lyapunov function was used as the critical condition that ensures the consistent convergence of the designed observers and the anticipative results of the states estimation.Then, the synthesis arithmetic of robust fuzzy sliding mode observer was designed by using LMI and pole placement approach, where the designed observer parameters were obtained by convex programming techniques for LMIs.Finally,the numerical simulation results were presented to demonstrate the design method and its effectiveness for an inverted pendulum.更多还原
