Digital Control of Power Stage Voltage


This example shows how to tune a high-performance digital controller with bandwidth
close to the sampling frequency.

Voltage Regulation in Power Stage

We use Simulink to model the voltage controller in the power stage for an electronic
device:

open_system('rct_powerstage')

The power stage amplifier is modeled as a second-order linear system with the following
frequency response:
