(a) Parabolic

(b) Ramp

(c) Impulse

(d) Step

This question was addressed to me in an interview for internship.

I want to ask this question from Parameter Optimization topic in portion Optimal Control Systems of Control Systems

Answer 1

The correct choice is (b) Ramp

Explanation: Velocity error constant of a system is measured when the input to the system is unit ramp function then only velocity error is finite but error due to other inputs are not defined.
