Abstract

This paper deal with the problem of unmeasured premise variable (UPV) in T-S fuzzy observer for ball and beam (BAB) system with friction. The observer design with UPV is rather challenging and with computational burden. Different from previous results to obtain the observer design condition based on a traditional TS fuzzy model, the work here presents a method by reformulating the BAB system as T-S fuzzy model with nonlinear consequent parts that has shown to reduce the number of fuzzy rules. The proposed method guarantees asymptotic convergence of state estimation. The conditions for the observer design is given in the form of linear matrix inequality (LMI) formulations. Simulation result illustrates effectiveness of the proposed method.

球梁系统的非线性Takagi-Sugeno模糊观测器设计[j]

研究了含摩擦球梁系统T-S模糊观测器中不可测前提变量(UPV)的问题。UPV观测器的设计具有一定的挑战性和计算量。与以往基于传统TS模糊模型获得观测器设计条件的方法不同，本文提出了一种将BAB系统重新表述为带有非线性后项的T-S模糊模型的方法，该方法减少了模糊规则的数量。该方法保证了状态估计的渐近收敛性。以线性矩阵不等式(LMI)的形式给出观测器设计的条件。仿真结果验证了该方法的有效性。
