The objective of the controller design in Fig. 1 is to find the controller Gc(s) such that I.)The closed-loop system is stable ii.)The output of the system above (y(t)) can track the reference input r(t) = At (A>0 is any real number). Use the Nyquist plot and Nyquist criterion to show that: a.)The portional controller Gc(s)=K can achieve asymptotic tracking of the ramp input r(t)=At but cannot meet the stability requirement for 0<K<+inf. b.) Can the PI controller Gc(s)=K(1+10/s) be...
