摘要
利用T-S模糊模型逼近一类非线性不确定时滞系统,将非线性系统模糊化为局部线性系统.基于李亚普诺夫稳定性定理设计出使模糊系统全局稳定的滑模控制器,该控制器对满足匹配条件和不满足匹配条件的不确定性系统均适用.最后以T ruck-T ra iler模型为例进行仿真研究,其结果验证了设计方案的可行性和有效性.
The T-S fuzzy model is used to approximate a class of nonlinear uncertain time-delay systems, and the nonlinear system is fuzzirized into local linear systems. The sliding mode controller is designed to make the fuzzy system global stabe based on the Lyapunov stability theorem, and the controller is suited to the system with matched or unmatched uncertainty. Simulation result of the Truck-Trailer model shows that the designed method possesses the feasibility and validity.
