基于黄金分割的船舶航向自适应控制方法研究 摘要 本文基于黄金分割的原理，研究了一种船舶航向自适应控制方法。通过对目标航向和实际航向的误差进行监测和分析，利用黄金分割法进行反馈控制，实现了船舶航向的自适应控制。实验结果表明，该方法具有良好的控制效果和稳定性，可以有效提高船舶的航行精度和安全性。 关键词：黄金分割；船舶；航向自适应控制；控制效果；稳定性 Abstract Inthispaper,ashipheadingadaptivecontrolmethodbasedongoldensectionprincipleisstudied.Bymonitoringandanalyzingtheerrorbetweenthetargetheadingandtheactualheading,usinggoldensectionmethodforfeedbackcontrol,theadaptivecontrolofshipheadingisrealized.Theexperimentalresultsshowthatthemethodhasgoodcontroleffectandstability,whichcaneffectivelyimprovethenavigationaccuracyandsafetyoftheship.
