Comparative analysis of magnetization curve models in terms of accuracy and applicability for variational optimization of electromechanical converters

The synthesis of optimum current obtained by mathematical models for an electrically propelled truck drive electromotor

“…However, considering the functional (11), we thereby attribute our problem of optimization to the isoperimetric class of problems [5,6], for we have to find out such law of the vehicle speed variation which would minimize the functional (10) on condition that the dynamics of the vehicle be describable by the relevant equation from the set (6)- (8), and the distance, covered by the vehicle, be set by the functional (11).…”

“…-as a relative value equivalent to the dynamic equation (8) of uphill motion, we obtain the equation…”

“…To complete the formalization of the problem, which we are to solve using the variational method [5,6], we have only to formalize, in the relative units, the magnetization curve ( ) i  , which, as shown in the work [7,8], is best generated for the variational method by the model…”
