In this paper, Takagi-Sugeno (T-S) fuzzy model approach is exploited to establish stability criteria for a class of nonlinear uncertain systems with time delay. The T-S fuzzy model is used to describe a nonlinear uncertain system in terms of fuzzy sets and fuzzy reasoning applied to a set of linear sub models. Moreover the system is considered in two conditions: the upper bound of the disturbance...
To alleviate the chattering problem, a new type of fuzzy global sliding mode controller (FGSMC) is presented. In this controller, the switching gain is estimated by fuzzy logic system based on the reachable conditions of SMC, thus the effect of Lugre friction on switch chattering can be alleviated. Moreover, global sliding mode is realized by designing an exponential dynamic sliding surface. Simulation...
