| 摘 要： | 针对船舶航向运动具有强非线性,并受各种不确定随机干扰的作用,提出了基于最小二乘支持向量机与变论域模糊逻辑的船舶航向保持复合控制方案,该控制方案利用最小二乘支持向量机良好的非线性映射能力建立船舶操纵系统的逆动力学模型,引入协调控制因子,与变论域模糊控制复合形成控制闭环,提高控制系统的控制精度和鲁棒性.仿真结果表明,本文所设计的航向保持控制系统效果良好,对海情的变化具有较好的自适应能力.

| Abstract: | A compound control strategy based on least squares support-vector-machine(LSSVM) inverse control and variable universe fuzzy control(VUFC) is proposed for a nonlinear process of ship motion subjected to random disturbances. This method utilizes the nonlinear mapping merit of the support vector machine inverse dynamic model and combines the fuzzy control to form a closed-loop control; it improves the control precision and guarantees the robustness by the coordination factor. The simulation results validate that the compound control algorithm has a high performance in ship course-keeping, and good adaptive ability in various ocean conditions. |
