用模糊逻辑实现动力定位船舶的艏向寻优

Optimization of Heading by Means of Fuzzy Logic

由于各种环境因素随时间不断变化，船舶作动力定位作业时，最优艏向也是不断变化的，所以艏向寻优是动力定位的关键技术之一。本文用模糊逻辑实现艏向寻优，其优点是：不依赖于环境要素的测量值和数学模型，寻优与控制相结合，反应快，准确程度高。

Since various environmental factors are everchanging,so the optimal heading for dynamic positioning vessel is everchanging as well. Thus the optimization of heading is one of the key techniques of dynamic positioning. This article introduces to realize optimization of heading by using of fuzzy logic which possesses the merits of independence from current models of measurement values and mathematics formular based on environmental factors; combining of control and optimization,quick response and high accuracy.
