Sliding-like fuzzy logic control with self-tuning the dead zone parameters

In this paper, a fuzzy logic controller (FLC) is designed based on the similarity between the FLC and the sliding mode control. The proposed scheme has advantages that it permits one to use more formalized, engineering type of knowledge to construct the FLC, and it provides the sliding-like FLC with fast self-tuning the dead zone parameters (boundary layer thickness) under parameter variations of the controlled system. Simulation examples using the proposed method for a rotary inverted pendulum are performed to show the properties of the developed FLC.
