Abstract

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 level
control of the coupled tank system. The FO-PI tuning rules based on fractional Ms constrained integral gain
optimization (F-MIGO) algorithm. The FO-PI controller is compared with both Ziegler Nichol's (ZN) tuned and
Modified Ziegler Nichol's (MZN) tuned conventional integer order proportional integral (PI) controllers in terms of load
disturbance rejection, changes in plant dynamics, and set point tracking. By Simulation results compare the FO-PI and
IO-PI in terms of percentage overshoot and system response in liquid level and flow control. The result confirmed that
fractional order PI controller is better than integer order PI controller.
