PID Controller Tuning For Buck Converter

PID Controller Tuning For Buck Converter

Tune the gains of a PID controller for a buck converter. There are a number of different types of converters, but the buck converter is the most commonly used. Pulse-width modulation (PWM) is used to quickly switch transistors on and off as needed.

A Simscape ElectricalTM buck converter is used in this demonstration. With pulse-width modulation, and the model is linearized to zero. A new PID tuning method in R2017b, Identification-based PID tuning, can be set up and run. Model linearization is no longer necessary to automatically tune PID controller gains. You'll also see how the tuned controller's performance is simulated to verify that it performs better than it did before.
