TAU, Solodovnikov, is it worth reading?

Question

Books

Is it worth reading the three-volume V. V. Solodovnikov "Technical Cybernetics: A Series of Engineering Monographs. The Theory of Automatic Control" 1967 in order to "understand" TAU or is this work obsolete? My tau level: listened to a semester of lectures and did not understand anything. Maybe there is literature recognized in the circle of engineers as the best for beginners?

Answer 1

TAU will not become obsolete, because it is based on higher mathematics :)
what I listened to and neither .... did not understand in TAU this is normal.

Answer 2

Yes, it's better to find a new one.
Two things need to be understood: stability (phase and amplitude margin) and the quality of the transient process.
Now there are a lot of textbooks. You can find something from foreigners.
