Best control technique for Boost dc-dc converters

[GeoAVR]

There are so many control techniques for boost converters (ie. type-3 compensation, sliding mode control etc).

I would like to know which one is considered the best.

Thank you

For the boost controller, it is necessary to have a controller with current mode because the inductor current is out of phase with the output voltage.

To choose a particular control, everyone has pros and cons. You need to give specifications such as speed, accuracy, ease of implementation, cost, ... to select the most appropriate control scheme.

Current mode control is probably best.

Constant off time control is also good sometimes.
Sometimes Boundary conduction mode is done as in BCM PFC's.

Constant frequency current mode needs slope compensation if duty >50%.

Voltage mode is possible and needs type 3.....but very few voltage mode controllers exist on the market.

if its just low power then just use burst mode control
