Webb12 apr. 2024 · After generating the PWM sine wave, it can be filtered using an inductor and capacitor to smooth out the waveform and remove the high-frequency components. The inductor with capacitor acts as a low-pass filter, allowing only the lower frequency components of the PWM signal (i.e., the sine wave) to pass through, while attenuating … WebbA cascade speed-control structure for a DC motor. A PWM controlled four-quadrant Chopper is used to feed the DC motor. The Control subsystem includes the outer speed-control loop, the inner current-control loop, and the PWM generation. The total simulation time (t) is 4 seconds. At t = 1.5 seconds, the load torque increases.
