外文摘要：A concise robust collaborative optimization control system of course-keeping autopilot with RRS is brought up to solve the multi-objective optimization problem in it. Firstly, the linear responding equivalent model is advanced to replace the nonlinear ship model in controller design. The course-keeping and RRS controllers are designed based on a robust PID algorithm, and the parameters of the above controllers are collaboratively optimized by NSGA-II with 3 objectives, such as the course-keeping accuracy, rudder roll reduction rate and the energy consumption of steering gear. Finally, simulation tests are done on half speed non-linear model of a naval carrier. The results indicate that the Pareto optimal set can represent the conditionality among the objectives. And the simulations based on the optimum solution achieve better course-keeping accuracy and roll reduction rate than empirical parameters. The system can overcome the uncertainty caused by model perturbation and external disturbances. ? 2015 ICIC International.
