Abstract：Ship load pressure tanks can become unstable in high seas as the waves lift and drop the ship. This study describes a ship pressure tank with automatic pressure control. A mathematical model of the tank is solved using a simulation model in AMESim and Matlab to predict the static and dynamic characteristics of the pressure tank. The pressure changes are then minimized using traditional PID and fuzzy PID methods. The results show that the traditional PID reduces the pressure variations by 77% while the fuzzy PID control reduces the pressure variations by 92% compared to those without control. Thus, the optimized fuzzy PID constant pressure control algorithm provides better control of the pressure stability in pressure tanks.
