| 摘 要： | 优化设计中的约束条件有许多是模糊的,用精确数学不能准确地描述这种情况。本文用模糊数学中的隶属函数来描述这种模糊边界,参照罚函数法的思想提出了一种新方法——模糊罚函数法,并用本方法进行了四杆机构轨迹综合的优化计算,获得了满意的结果。

| Abstract: | Many constraints in optimization are fuzzy constraints,which can not be exactly described by accurate mathematics .In this pape-these constraints are described by membership functions of fuzzy mathematics, and a new method, named The Method of Fuzzy Penalty Functions, is presented. The method has a better stability and shorter time in computation. As an example, the optimal synthesis of a four-bar linkage for path generation is done with this method, and the result is satisfactory. |
