This paper presents the PI controller design for coupled tank as Single Input Single Output (SISO) process using Characteristic Ratio Assignment (CRA) method.CRA is an approach to directly control the transient response of linear time invariant control systems. The transient response for all pole transfer function of nth order system can be controlled by introducing a set of parameters(αi) characteristic ratio, (i=1,2,…,n) and (t)generalized time constant.The CRA method which satisfies more specification and performance of control system. The coupled tank as SISO process is a challenge plant for testing the performance of PI controller. The fundamental model of coupled tank as SISO process is obtained and CRA based PI controller is designed. Using a CRA-PI controller the simulation results has been simulated by MATLAB and real time results also can be implemented for coupled tank as SISO process.
