It has been shown that the structural and parametric synthesis is the main way to ensure the working capacity and the set quality level of the automated electric drives (AED) at all stages and phases of their life cycle. At the same time the structural synthesis assumes the selection of the AED construction option, and the parametric synthesis is directed to determination of nominal values of the electric drive internal parameters and the permissible limits of their change at which the electric drive maintains the operating state. It has been established that a set of AED quality indicators formation and synthesizing the optimality criterion are necessary to solve the problems of structuralparametric synthesis. The AED morphological analysis is performed, its structure is defined, it has been shown that in many cases the multi-mass mechanical system of the electric drive can be reduced to a dual-mass calculation scheme. The classification of control and disturbing influences of the AED is considered, and the parameters characterizing its state have been established. The AED quality indicators are analyzed and a conclusion on their use in relation to a problem of structural and parametric synthesis is made. It has been established that the decisive role in selecting the AED structure is provided by the technical and economic indicators, and to solve the problem of parametric synthesis such indicator is the working capacity resource characterizing the AED parametric reliability at limited statistical information on the laws of changes in the parameters of its elements. The optimization methodology in relation to the structural-parametric synthesis of AED based on specially introduced postulates is developed. Based on the obtained results, a conclusion on the necessity to use the working capacity resource at the parametric synthesis of AED, as well as expediency of its application as an objective function at limited information on the laws of changes in the AED internal parameters or its complete absence, is made. It has been shown that the information on the working capacity resource is also necessary for the structural synthesis of AED. Moreover, it can be recommended also as the optimality criterion.

При этом структурный синтез предполагает выбор варианта построения АЭП, а параметрический синтез направлен на определение номинальных значений внутренних параметров электропривода и допустимых пределов их изменения, при которых электропривод сохраняет работоспособное состояние. Установлено, что для решения задач структ...
