A new switching function is constructed to weaken chattering and keep robustness of the sliding mode control. The control structure switching should occur when movement trend of system state changed relative to the switching surface. This will guarantee that different control structures have equal output on the switching surface. The new switching function introduces pseudo-sliding surface, and a...
Beginning with the reasons of chattering, this article proposes two new sliding mode reaching laws. In one hand, they guarantee the system reach the switching surface rapidly and remain on it, in another hand, they suppress or weaken the chattering effectively, such that the system response can better realize the unification of rapidity and stability. At the same time, the article provides the specific...
