Abstract: In this paper, the structure of the P-I controller has been revised to I-P controller structure, for the model of First-order plus time delay and model of Half-order plus time delay. P-I controller is the dominant controller used for most of the Industrial processes. However, high peak overshoot is one of the disadvantages faced by P-I controller. The objective of this study is to overcome this disadvantage, I-P controller has been implemented. Simulation results obtained using MATLAB/simulink shows that the I-P controller tuning approach provides enhanced performance and reduction in the peak overshoot when compared with P-I controller tuning.
