Interval type-2 fuzzy logic system for the double tank water level control system
Wen Zhang, Ruisheng Sun · 2017
Interval type-2 fuzzy sets used in fuzzy logic system was called interval type-2fuzzy logic system. For high-order big inertial object, the good control effect cannot be reached if normal PID control method is employed. In this paper, a interval type-2 fuzzy controller is designed based on fuzzy control theory. It can automatically modulate parameters in real-time according to the deviations and the varying rate of deviations. MATLAB simulation results show that this fuzzy controller can provide better control effect than normal PID controllers, and can greatly improves the dynamic and stable performance of the system.
