摘要
针对一类非线性系统,基于T-S模糊模型提出了一种变结构控制算法.采用带有非匹配参数不确定性和时变时滞的T-S模糊模型来近似代表原非线性系统,使用线性矩阵不等式设计了一个渐近稳定的滑模面,所设计的控制器能够克服时变时滞和不确定性因素的影响.仿真结果表明该算法具有良好的稳定性和鲁棒性.
A variable structure control algorithm based on T - S fuzzy model for a class of nonlinear sys- tems is proposed. The nonlinear system is approximately represent by a T - S fuzzy model with mismatched pa- rameter uncertainties and time - varing delay. By linear matrix inequality, an asymptotically stable sliding sur- face is proposed. The controller can overcome the effect of the time - varing delay and uncertainties. The sim- ulation results demonstrate that the stability and robustness of the algorithm are good.
