Abstract

Inherent nonlinearities like Dead-band, Stiction, and hysteresis in control valves degenerate plant performance. Valve Stiction standouts as a more widely recognized reason for poor execution in control loops. Measurement of valve Stiction is essential to maintain scheduling. For industrial scenarios, loss of execution due to nonlinearity in control valves is an imperative issue that should be tackled. Thus, an intelligent technique is required for automated execution, observation, and enhancement. The paper shows the creative utilization of an intelligent controller for nonlinearity diagnosis in control valves. This is a Fuzzy gain scheduling (FGS) PID smart controller that tunes its gain parameters in real time to manage a control valve’ s inherent nonlinearities. The viability of the FGS PID controller is experimentally verified in a laboratory scale plant. An execution comparison between FGS PID and classical PID controllers are undertaken for their setpoint following and disturbance rejection at different operating points. Experimental results show that the FGS PID controller outperforms the classical PID controller for all explored cases effectively managing Stiction based oscillation in the controller output.
