The application of fuzzy smith-PID controller in coupled-tank liquid-level control system

摘要

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 king view, the monitoring interface is designed, and the Liquid-level control system is practiced. The result shows that this method is rationality and feasibility.
