PARAMETERS IDENTIFICATION OF A PERMANENT MAGNET DC MOTOR

摘要

In this paper, driver circuits and parameters identification of a permanent magnet dc motor are addressed. To identify the parameters of the motor, an experimental measurement of armature voltage, armature current and rotor speed are performed using the NIDAQ USB-6008 data acquisition module. DAQ toolbox and Simulink in MATLAB are used to acquire the test signals and perform analysis based on the nonlinear least square method. The extracted motor parameters produced consistent simulation results with experimental data. The proposed approach proved to be simple, fast and accurate.
