Özet
In this paper, a class-C chopper circuit is modeled using z-transformation including the time variation of pulsewidth modulated (PWM) signal, and then a closed-loop speed control system using a direct current (dc) motor fed by the chopper is simulated. In the simulation, the entire system including de motor, chopper, speed and current controllers are all modeled in z-domain. Simulation has been performed with the help of Matlab and Simulink. In addition, the closed-loop system has also been analyzed according to the average value modeling and the results obtained from the real-time simulation in z-domain are compared with the results obtained from the average value model.
