I'm new to this "forum", I'm studying control engineering...
While studying this area, one of our lecturers told us that a lot of information is lost when one treats control only from a transfer function point of view.
So what I want to know is, if there are references that manages control from only differential equations or similar and explains basic and completely how to treat controllers from this point of view, could you please point me to some of them.
Note: Being even more specific how do you design controllers if you couldn't use the Laplace transform.
Thanks in advance.
