PERFORMANCE COMPARISON OF FRACTIONAL ORDER PID CONTROLLER AND LINEAR QUADRATIC REGULATOR FOR LEVEL CONTROL IN COUPLED TANK SYSTEMS

Abstract

Process control is essential in the industrial process because it guarantees the safety and optimization in a process. Additionally, process control is a useful tool to satisfy the environmental procedure and product quality necessities. In industries, one of the controlling process variables are level process, the liquid level controllers are asignificantconcern popular process &collectiveillustrativealsoreal-world in engineeringmethods, liquid level coupled tank system, and can be arranged fashionable form of interacting and non- interacting, in this thesis work only focus on interacting coupled tank control systems, industries there many problems which affected the liquid level, so to overcome this problem and obtain constant stable output and fast response various controllers are required. In the automated function of the interacting container, the scheme is commonly recycled exclusively in the level process. A mechanism to regulate the process height in container and movement among tanks are problematic in the process automation. Industrial engineering requires fluid moved and reserved in a container, and then stirred to another to the container. This thesis work presents the improvement concerning sectional order (FOPID) and Determinate the Optimal controllerfor governinga desired liquid level of the tank system. Various fractional-order (FOPID, Crone, TID, and FOLL) controllerand control techniques will be tested to get a great performance. the output response is conducted within MATLAB®/Simulink®situation to verify the performances of the system in terms of rising Time (Tr), Settling Time (Ts), and Overshoot (OS).from the controller included in this thesis work the Linear quadratic regulator with integral action (LQI) controller have better performance compare to the other, the overshot 7.690% and rise time218.48𝑚𝑠𝑒?
