Research on a Stable Adaptive Fuzzy Control of Nonlinear Liquid Level System

Abstract

Based on the theory of variable universe fuzzy control and Lyapunov stability, a stable adaptive fuzzy control for time-varying nonlinear liquid level system is proposed. The solution uses the stable adaptive law based on variable universe without system identification, and its improved control compensator has the characteristic of easier setting. The simulating results demonstrate the effectiveness of this approach.
