Abstract: This paper is concerned with the study of PID i.e. Proportional, Integral and Derivative Controller. PID controller is used in the various process industries because of their simplicity, robustness as well as successful practical application. In this study, the PID controller is applied for a second order process to obtain the fast rise time, no overshoot and no steady-state error.

Keywords: P, PD, PI and PID Controller, Closed loop system.
