Control systems engineering and Digital signal processing are both important courses/subjects of electrical engineering But how these two subjects/courses are related to each other??

Also please kindly let me know,what are some recommended resources (books, tutorials, lectures, etc.) on control systems engineering, and how to begin working with it on a technical level?

As we have answer in below link but that answer is about dsp resources, I am looking for resources about control systems engineering [example answer of refrence request](https://dsp.stackexchange.com/questions/427/what-resources-are-recommended-for-an-introduction-to-signal-processing-dsp)
