The Application of Fuzzy Smith-PID Controller in Coupled-Tank Liquid-Level Control System

Abstract:

To resolve the problem of lumping lag and nonlinear of the coupled-tank liquid-level control system , a fuzzy Smith- PID control approach is researched. In this approach, the characteristic of the control system is analyzed，the fuzzy Smith- PID controller is designed. In kingview, the monitoring interface is designed, and the Liquid-level control system is practiced.The result shows that this method is rationality and feasibility.
