Considering the characteristics of industrialized mariculture, a two-order delay mathematic model of water temperature regulation system is constructed, Smith compensator is designed and simulated in MATLAB environment. The obtained results show that the proposed Smith compensator is stable, reliable and responded rapidly compared with direct PID control. It has minor settling time and excellent dynamic and steady-state characteristics.
