When applied to switch mode power supplies, the most common control methods are Voltage Mode Control, Peak Current Mode Control and Voltage Mode Control with Input Voltage Feedforward.
In this video, Dr Seyed Ali Shirsavar of Biricha Digital will explain, in his easy to follow way, how these control methods work, what their advantages and disadvantages and which one is most suitable for your application.

Awesome. Thank you for this direct explanation. It helps contextualize the control schemes I've seen and clarifies the advantages and disadvantages.

A pleasure to follow your teachings on all these subtleties and techniques of power electronics. Regarding your series on capacitors, which capacitor technologies would be most appropriate for the creation of compensation networks (error amplifier) of SMPS ? Thank you

I'm not the poster, but I believe ceramic caps are pretty common for the PI / compensation amp. They have good capacitance density so they can be quite small. X7R dielectrics are pretty common; they have good capacitance density (lot of capacitance in a small package), usually have a ±10% tolerance but the capacitance has some voltage dependence. C0G dielectrics are also available; they have lower capacitance density but have very little voltage dependence and are available with ±5% tolerance. X7R is usually good if you need a larger capacitance and / or precision is not too important like filtering applications and C0G is generally better for applications where precision is important like setting a precise delay time. There are other ceramic dielectrics available that you can check out if you're curious.

Please make video on slope compensation

I heard that Current Mode is easier to compensate compared to Voltage Mode, for there is no complex conjugate poles. Is that correct?

Yes that's correct. But current mode comes with lots of other challenges like leading edge blanking, slope compensation, current sensing

verrrrrrrrry nice but why are you using paper ! what's the problem with whiteboard ? i think using paper is not good for something like that
