In order to achieve efficient control of ship course keeping with low energy consumption, this paper introduces nonlinear feedback into fuzzy control and closed-loop gain shaping algorithm (CGSA). Taking the ship “New Triumph” as an example, the simulation results show that the multimode controller with non-linear feedback can not only respond to the steering instructions quickly, but also reduce the energy consumption by 32% to realize the course keeping efficiently and smoothly under the wind-wave model. Research shows that the introduction of nonlinear feedback term can optimize the control system, and its advantages of saving energy consumption are of great significance in practical engineering applications.
Key words: Course keeping / Efficiency-improved control / Nonlinear feedback / Multimode algorithm
