This paper includes the comparative study of fractional order proportional integral control system (FO-PI)and Integer order proportional integral control system (IO-PI). In this paper both controllers are used for the water levelcontrol of the coupled tank system. The FO-PI tuning rules based on fractional Ms constrained integral gainoptimization (F-MIGO) algorithm. The FO-PI controller is compared with both Ziegler Nichol's (ZN) tuned andModified Ziegler Nichol's (MZN) tuned conventional integer order proportional integral (PI) controllers in terms of loaddisturbance rejection, changes in plant dynamics, and set point tracking. By Simulation results compare the FO-PI andIO-PI in terms of percentage overshoot and system response in liquid level and flow control. The result confirmed thatfractional order PI controller is better than integer order PI controller.
