Abstract

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 example for flight simulator servo system with Lugre friction model is given to indicate that the proposed controller can guarantee high robust performance all the time and can alleviate chattering phenomenon effectively
