I am highly interested in the study of control systems theory. However it seems that almost all books are written by electronics or mechanical engineers.
Due to this they generally omit many things. For instance every single textbook in controls explains the DC motor, the RC circuit state space models. However I yet have to see a book that says something like,
Feedback loops in nature: When a car is being driven air resistance is proportional to speed and constitutes a 'natural' feedback without any op-amps or sensors etc...
and feedback loops in weather
https://www.theguardian.com/environment/2011/jan/05/climate-change-feedback-loops
if anyone knows of a book that addresses such matters that will be great!
