Adaptive MIMO Fuzzy Controller for Double Coupled Tank System optimizing by Jaya Algorithm

摘要

This paper proposes an adaptive MIMO fuzzy controller optimized with Jaya optimization technique used to robust control of uncertain coupled tank system. Firstly, the parameters of MIMO fuzzy controller are optimally identified using Jaya algorithm. Then a fuzzy sliding surface is implemented to ensure that the coupled tank system is asymptotically stable based on Lyapunov concept. The proposed algorithm is applied to control the fluid level of double tank systems. The comparison results with PID and traditional fuzzy controller are presented to confirm that the new Adaptive MIMO Fuzzy control method proves a robust and simple approach to effectively control highly nonlinear uncertain systems.
