一、引言 电机电器的优化设计一般是指在“满足性能指标要求的前提下,使设计的电机电器最优”这样一个概念。鉴於此,优化过程就涉及到目标函数的建立,约束条件的确定和变量的选取等几个方面的内容。 在实际问题中,变量的变化有离散的;有连续的;目标函数式就业加复杂,有的函数本身不能解析,这样在函数不易求导或导数不存在的情况下,广泛地采用了直接法。 我们在工作中曾经对异步电机设计中的 First, the introduction of electrical and mechanical optimization design generally refers to “meet the performance requirements of the premise, the design of electrical and mechanical optimal” such a concept. In view of this, the optimization process involves several aspects such as the establishment of objective function, the determination of constraints and the selection of variables. In practical problems, variables change discrete; continuous; objective function employment plus complex, and some function itself can not be resolved, so that the function is not easy to derive or derivative does not exist, the widespread use of the direct method .
