Requirements :
1. the gain crossover frequency w_c should be approximately (+/- 10%);
2. the steady-state error should be zero in response to a unit ramp reference;
3. the phase margin should be at least 60 degrees;
4. the effect of measurement noise on the output should be attenuated by at least 1/100 at noise frequencies
w > w_2.
This my O.L.T.F.
Choose Ti and k such that design criteria 1 and 2 are both met, and the system remains stable. (Hint: choose
Ti first to eliminate steady-state error, then select k to set the gain crossover frequency).
With this choice of controller, demonstrate whether design criteria 3 and 4 are met.
