BARC EE : Control Systems Quiz-2

What is the overall transfer function of the block diagram given above?

Gain margin of the standard second order under damped system is

A unity feedback control system has a open loop transfer function , So the steady state error when it is subjected to the input. r(t) = 1 + 2t + 1.5t² is

For a system transfer function , Find the zero-state response when the input x(t) is e^-3tu(t).

Consider the open loop transfer function of a system with

For complex root loci the center and the radius of the circle is

In the system of figure. , (Assume k>0) the system is stable for.

The value of the steady state error for first order system,  with Unit Ramp Function will be

The system is originally critically damped. If the gain is doubled then it will become:

The state space representation and transfer function of a system is

TF = the elements c₁ and c₂ respectively are
