Can you help me (show me how) to solve the following exercise?

For the process with transfer function $G(s)=e^{-2s}/(s+1)$ design a digital controller with sampling time $T_{s} = 1$ that meets the specifications:

  1. $e_{∞}$ (steady state error) null whit a step as input;
  2. dominant poles in closed loop with damping $ζ≥0,5$;
  3. settling time $T_{a1}≤20sec $.
  • $\begingroup$ Did you mean $e^-2s$ or $e^{-2s}$ ?? $\endgroup$ – Peter K. May 4 '13 at 12:06

    $\begingroup$ @Peter K. - I mean the second one: exp(-2s). $\endgroup$ – Backo May 4 '13 at 19:04
  • $\begingroup$ This is trivial, but i figure this homework expired so long timeeeee... $\endgroup$ – Brethlosze Nov 14 '16 at 7:25
