Identification and synthesis of the models electromechanical energy converters

Abstract

The results are given of computer simulation of electromechanical converters (EMC) - asynchronous and synchronous motors (AM and SM). Models make it possible to carry out the simulation of different regimes. All input characteristics and disturbances can be determined or random processes. The simulation result is a complete set of electromagnetic and mechanical characteristics. The connection between inputs and outputs of the models was determined by the solution of the problem of identification by the selected channel and the synthesis of the adequate electrical circuit (AEC), electromagnetic processes in which were equivalent to processes in EMC. Methods of statistical uncertainty (MSU) were used as the identification methods - the solution of the Wiener-Hopf equation and the frequency response method (FRM). The identified function is the impulse transient function (ITF). ITF approximation is conducted using positive real functions (PRF), which determine the physical realizability of the synthesized adequate circuit.
