control systems

[whatty]

Hi there now i had studies the basics in  control system theories now i am interested to learn designing control systems for dc to dc converters so can anyone suggest me a book which explains with examples in dc to dc converters or any power electronic controller how feedback loop implemented or how the system is designed it should have worked examples too.

Thank you in advance..

TI, Analog and the other IC manufacturers tend to have decent papers associated with each product.  Maybe do a search?  I came up with this paper rather quickly: https://www.ti.com/download/trng/docs/seminar/Topic%206%20-%20DC-DC%20Power%20Conversion%20and%20System%20Design%20Considerations%20for%20Battery%20Operated%20System.pdf

Have a look about the pdf below.
It's 63 pages about using the TL431 and designing a control system around it, inclusive handing of an optocoupler in the loop.
