Question

(a) Proportional error controller

(b) Derivative error controller

(c) Integral error controller

(d) One plus derivative error controller

I got this question by my college director while I was bunking the class.

I would like to ask this question from Control Laws in FBW in division Fly by Wire Flight Control of Avionics

Answer 1

Correct choice is (d) One plus derivative error controller

The best I can explain: A phase advance controller is usually known as phase advance controller with a transfer function.

The control term is filtered to limit the increase in gain at high frequencies and smooth the differentiation process which amplifies any noise present in the error signal.
