Abstract

Many existing stability analysis methods for fuzzy logic control systems like TS fuzzy model based methods usually tackle plants that are linear with respect to control. However, these methods may be difficult to apply to plants with dead zones. This paper presents an improved stability analysis method to resolve this difficulty. Our proposed method employs a Lyapunov function to prove the stability of non-linear fuzzy logic control systems with asymmetric dead zone and saturation. An illustrative example will be given to demonstrate the ability of the method.
