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...

How do people tune internal dc-dc converter controllers when operating in parallel with other converters in a dc microgrid network?

From looking at books and academic papers, it seems to me most people tune internal voltage controllers in dc-dc converters assuming other paralleled converters in the network are tightly...

How internal voltage or current loop controller should be designed in parallel droop controlled dc-dc converter network?

When paralleling droop controlled dc-dc converters, should the internal voltage and current loop controllers be designed to account for other paralleled converters in the network? Currently I've...
