An approach of parameter identification for asynchronous machine

This work deals with the parameter identification of asynchronous machines in cases where the motor is rotating and at standstill. In this work, an optimal exciting input signal is determined by methods of optimization to give a best trajectory of the system. Integration is applied to a differential...

Description
Summary:This work deals with the parameter identification of asynchronous machines in cases where the motor is rotating and at standstill. In this work, an optimal exciting input signal is determined by methods of optimization to give a best trajectory of the system. Integration is applied to a differential equation model to avoid the wrong information caused by a derivative operation on noise. Instrumental variable estimation is introduced to improve the quality of identification by least-square estimation. Experimental results are given. The work is achieved with MATLAB Toolbox.
