Question

The optimal control at each state is ________ combination of states.

(a) Linear

(b) Non-linear

(c) Time variant

(d) Time invariant

I had been asked this question in an internship interview.

My query is from Optimal Control Systems in section Optimal Control Systems of Control Systems

Answer 1

Right option is (a) Linear

For explanation I would say: The optimal control at each state is linear combination of states and thus giving the linear state variable feedback control policy.
