Experimental Identification and Control of a 3Kw DC Motor

Abstract

In this project, it was requested to identify the parameters of a 3Kw DC machine to realize a speed control of this machine using a Dspace1103 acquisition card. The control consists to generate a PWM signal to manage a buck chopper based on an IGBT. The proposed control is based on two Proportional-Integral (PI) controllers to regulate both, the speed and the current of the identified DC motor. For this purpose, tests were carried out in order to identify the parameters of this machine. This was followed by the practical implementation of our control system. In order to validate our test bench, several diagrams and explanations have been presented in this paper. The proposed algorithm has been investigated through simulation using the MATLAB/Simulink environment and validated experimentally on a laboratory prototype using Dspace1103 real time board.
