Analysis of Fuzzy Based Level Controller for Non-Linear Process Tank

P Aravind, M Valluvan

This article deals with an application of rule base algorithm used to obtain satisfactory response for a non linear process. In this work, a control of liquid level in the conical tank is studied and identification of process is performed through Step response method in simulation environment. The process dynamics of the level process in the conical tank is described by the differential equation. Then the controller tuning strategy has been applied using direct synthesis PI tuning method and the rule based algorithm based fuzzy logic controller has been implemented. The simulation results are obtained and compared to evaluate the performance of fuzzy logic controller based on rise time and settling time.
