Abstract

Abstract

In order to improve the safety and comfort of ship navigation, a kind of rudder-fin joint control system was designed to make ship have good course-keeping and roll-damping effects, a closed-loop gain shaping algorithm for multi-input multi-output (MIMO) system was presented by constructing the transfer function matrix of the closed-loop system according to prior knowledge, four parameters with engineering meaning, such as bandwidth frequency, high frequency asymptote slope, the largest singular value and the peak value of closed-loop frequency spectrum, were used to construct the matrix.The designed algorithm was applied to a rudder-fin joint control system, its simulating curves were obtained using Simulink.Simulation results show that the controll system has well control performances on course-keeping and roll stabilization, the average roll angle range is from +2° to-2°, and the maximum roll angle is 4°.
