    Evaluation of discrete modeling efficiency of asynchronous electric machines
    (Видавництво Львівської політехніки, 2011) Byczkowska-Lipińska, Liliana; Stakhiv, Petro; Hoholyuk, Oksana; Vasylchyshyn, Ivanna
    In the paper the problem of effective mathematical macromodels in the form of state variables intended for asynchronous motor transient analysis is considered. Their comparing with traditional mathematical models of asynchronous motors including models built into MATLAB/Simulink software was carried out and analysis of their efficiency was conducted.

    Peculiarities of construction of electromechanical converters’ macromodels with the use of optimization process
    (Видавництво Львівської політехніки, 2012) Stakhiv, Petro; Kozak, Yuriy; Vasylchyshyn, Ivanna
    In this paper the new approach to the simplification of optimization problem of macromodels construction is suggested. The approach is based on a slight deviation from the black box principle and taking into consideration physics processes that occur in the object of modeling.
