Question:medium

The steady state error for a type 1 system with input of \[ \frac{At^2}{2}u(t) \] is

Show Hint

Steady-state error for unity feedback systems: \[ \begin{array}{|c|c|c|c|} \hline \text{System Type} & \text{Step} & \text{Ramp} & \text{Parabola} \hline 0 & \text{Finite} & \infty & \infty 1 & 0 & \text{Finite} & \infty 2 & 0 & 0 & \text{Finite} \hline \end{array} \] A Type-1 system always has infinite steady-state error for a parabolic input.
