Is it possible to augment the control signal (e.g. PWM) of a dc-dc power converter with external controller?

I'm wondering from a practical point of view whether or not it's possible to augment the control signal (e.g. PWM) from the internal voltage controller of a dc-dc boost converter bought from say...

Limitations of Linear Quadratic Regulator in non-minimum phase systems?

I understand the bandwidth limitations of feedback controllers in non-minimum phase systems (unstable zeros attract LHP poles to RHP). Classical controllers can deal with this rather easily by...
