Abstract

For the problem that not all the state variables used in the ship dynamic positioning control system can be measured, a model predictive controller of ship dynamic positioning with state estimator was designed to improve the control accuracy of the system. A comparative analysis through the simulation of the model predictive control with or without constraints was made, and state estimator was conducted based on MATLAB. Results show that the model predictive control of ship dynamic positioning with state estimator can improve the control effect of dynamic positioning, the effectiveness of this proposed control arithmetic was validated.

Key words： ship; dynamic positioning; model predictive control; state estimator
