Multi-domain physical modeling software with an intuitive simulation methodology using MapleSim was adopted in this study to create a rigid body structure model of an active transverse anti-rolling system (ATARS) of a container ship. At the same time, a ship stability analysis was also conducted to determine the force model, dynamic equilibrium, and motion behavior of the ATARS of the container ship. Once various external transverse force generated by waves impact varied roll angles of the ATARS on the vessel, a modified proportional-integral-derivative (PID) controller designed to improve the capability of the active stabilizer fins used in the ATARS is applied to reduce the roll angle. Consequently, using the modified PID controller, the maximum overshoot, roll angle, and steady-state error of the designed container ship were determined to be 11.2°, 340 s, and 6.1°, respectively.
