In this study, the dynamic model extraction of the three-phase squirrel cage asynchronous motor driven with a voltage source inverter and the system identification for the speed control has been applied. The transfer function of the system corresponding to the dynamic behavior of the asynchronous motor in real time was found by using the System Identification Toolbox in the MATLAB/Simulink program. By using the transfer function found for system, a simulation block diagram was executed. To keep the change in asynchronous motor speed within the desired tolerance limit values, the gain coefficients of PI controller was adjusted automatically by making a simulation study. The gain coefficients of the controller found as a result of the simulation study were applied without any change to the same asynchronous motor that was operated in real time. It has been determined that there was no deviation that might negatively effect the steady-state operation at motor speed against to mechanical load changes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
