Abstract: According to the requirement of ship Dynamic Positioning simulator control simulation system, a model predictive control scheme was proposed for DP simulator with the proportional integrator. Ship Dynamic Positioning simulator was mainly used for training and competency assessment of DP operator. At present, DP Simulator mainly depends on imports and there is no domestic DP simulator with independent intellectual property rights. Dynamic Positioning controller is one of the key technologies, which determines the performance of DP simulator. Considering the unknown slowly-varying marine environment disturbance and vessel constraints, a dynamic positioning controller was designed based on the model predictive control with proportional integrator. The controller could overcome the environment disturbance by the constrained force to reach and maintain the desired position and heading. The simulation experiments verify the effectiveness of the proposed algorithm.
