Abstract

Design concepts of tracking adaptive electromechanical control systems of limit speed with the use of reference models ensuring adaptation both to the change of the control object parameters and certain changes in the environment are considered. The functional structure of electromagnetic systems with reference stationary models and signal self-adjustment supported by digital adapters, as well as specifics of their synthesis providing implementation of two control rates, is considered. For adaptation to parameters of external influence and, as a result, to the modes of functioning of an electromechanical control system within the zones of “small” and “large” coordinate deviation, the functional structures of the servo electric drives are supplemented by adaptive reference models installed at the input of the closed control systems and serve as a specific power-up sensor. Results of simulation modelling of the electromechanical system with the adaptive reference model in the Matlab/Simulink environment confirming the effectiveness of the proposed approaches are given.
