|Title||Parameters Identification of A Permanent Magnet DC Motor|
In this thesis, driver circuits to drive DC motor are designed and built. We take in our design the safety for any damage, the isolation from any interference and the capability to provide the sufficient current needed to drive the motor. Also, methods and algorithms used for parameters identification are addressed. Data acquisition module form National Instruments is a suitable module used for acquiring signals since it’s compatible with MATLAB and LABVIEW. 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. Trials are performed to apply some of the methods on the motor practically to identify the motor parameters. DAQ toolbox in MATLAB/Simulink is used to acquire the test signals and perform analysis based on the nonlinear least square method or pattern search method which they are suitable. Finally, we designed a GUI to be user friendly and to automate all the process of identification, in addition to the feature for undergraduate and graduate students to apply experiments on control and machine labs. The extracted motor parameters from simulation produced consistent simulation results with experimental data. The proposed approaches are compared and both are proved to be simple, fast and accurate.
