MODELING OF CONTROLLED DC MOTOR WITH A CHOPPER CIRCUIT

Abstract

To design a control system for any system, it is required to model the system's dynamic behaviour. The modeling and analysis of these systems can be either numerical or analytical. This paper studies the analytical methods of modeling DC motors mainly continuous-time averaging technique and discrete-time approach. It shows that the discrete-time approach provides clear expressions representing the operation of DC motors and thus can help designers gain a better understanding of the performance of the motor. The results are shown using numerical simulations.
