I've got a question on the Nyquist Stability criterion.
Consider a unity negative feedback system with plant L(s) and gain K in the forward loop.
A nyquist plot is to be generated for this system to meet the following criteria:1) L(s) has one unstable right half plane pole
2) The closed loop system is stable for (1/3 < K < 2) and unstable for K=1/3 and K=2.3) Phase margin of 30 degrees
4) Zero steady state error to a step reference input.
