Pid controller for nonlinear interacting two tank liquid level control
Couple tank system is often used in chemical process industries to process the various liquids in the tanks. The control of liquid level in tanks and flow between the tanks is a problem in process technologies because of interaction between the tanks. The process technologies require liquid to be pumped, stored in tanks and then pumped to another tanks systematically. In this paper an efficient elementary idea about the PID controller for liquid level process for couple tanks system has been presented.
