Feedback is :(a) Linear(b) Non-linear(c) Time variant(d) Time invarian

1.	Feedback is :(a) Linear(b) Non-linear(c) Time variant(d) Time invariantI had been asked this question in class test.The origin of the question is Optimal Control Systems in portion Optimal Control Systems of Control Systems
Answer» Correct OPTION is (C) Time variant To explain I would say: Feedback is time varying all the optimal policy converts a linear time invariant plant with time invariant QUADRATIC PERFORMANCE index into a linear time varying feedback system.
