摘要：AbstractThis paper considers the use of a simplified dynamic window (DW) algorithm to handle actuator magnitude constraints for a 3 degrees-of-freedom dynamic positioning controller for ships. To accomplish this, we use the simplified DW algorithm to design a dynamic window-based controller (DWC) which guarantees that the velocities remain within a feasible set, while simultaneously respecting the actuator magnitude constraints. The DWC is compared with a benchmark motion controller which uses nonlinear position and velocity feedback terms. The comparison is made using performance metrics which consider both control accuracy and energy efficiency.
