abstract = {The mathematical model for two interacting conical frustum tank level (TICFTL) process is proposed. The control of TICFTL process is difficult due to the nonlinearity, interaction effect between input flow and output level of tanks. Hence, the nonlinear process is linearised around proper operating points. Then, the decentralized PI, centralized PI, centralized FOPI controllers are designed and then the control parameters are tuned using genetic algorithm. The closed loop controller performances are simulated and compared in terms of settling time, rise time and integral error criteria. It is found that centralized PI controller has better servo and regulatory response than the decentralized PI, centralized FOPI controller. The liquid inflow rates are optimally manipulated by the centralized PI controller to track the set point variation and to reject the disturbance effectively than centralized FOPI, decentralized PI controller.},
