代码说明:

  傅立叶变换能将满足一定条件的某个函数表示成三角函数(正弦和/或余弦函数)或者它们的积分的线性组合。(Fourier transform can meet certain conditions expressed as a function trigonometric (sine and/or cosine functions) or their integral linear combinations.)

    in this work we have tried to control a tanker ship using fuzzy logic and fuzzy controllers. it s well known that we can use fuzzy logic for control purposes in two ways,first we can use fuzzy logic to make a model of the plant and use conventional controllers to control the whole system controllers like PID,or nonlinear methods like Sliding mode control or ... on the other hand we can use fuzzy logic algorithms and methods for direct control of the plants. in this work we have used the second one and have propsed a fuzzy algorithm to control the tanker vehicle directly.

    为判断聚类结果质量的好坏,需要一个客观的评价指标来评价聚类结果的合理性。聚类性能评价方法通常分为三种:外部评价法,内部评价法,相对评价法。外部评价法将聚类结果得到类标签和已知类标签进行比较,此评价法的前提是数据集样本的类标签已知(In order to judge the quality of clustering results, good or bad, the need for an objective evaluation to assess the reasonableness of the clustering results. Clustering performance evaluation method is usually divided into three types: external evaluation method, internal evaluation method, relative evaluation method. External evaluation method of clustering results to obtain class labels and the known class labels are compared, the premise of this evaluation method is a class label known sample of the data set)
