Plant linearization is achieved by injecting perturbations into the plant to estimate frequency response models for the inner and outer loops. You’ll see how to use the PID Tuner from Simulink Control Design to tune the controller using outputs from a linearized plant model. The cascaded controller setup is modeled in Simulink and controls the inner inductor current loop and the outer voltage loop. The passive components like the diode bridge rectifier and the boost converter are modeled in Simscape Electrical™. In this video, you’ll learn how to use Simulink ® to perform power factor correction by modeling a PFC boost converter and tuning controller gains to achieve a power factor near unity. Power factor correction (PFC) is a way of increasing a power supply’s ability to deliver real power.
