Abstract
Output feedback sliding mode control has received great research interests,because it does not require full accessibility of states and increases the ability of practicalimplementation of sliding mode control. In this paper, a new approach of chattering-freeOFSMC design is proposed by incorporating integral sign function control for generalmulti-input multi-output linear uncertain systems. Compared with the boundary layertype chattering-free designs, the complete robustness to system matched disturbances oruncertainties has not to be sacrificed and the global attractiveness of the sliding surfacecan be achieved through the controller synthesis.
