본문내용

1. For the following block-diagram, perform the given problems using th Matlab.
1) Determine the stability of the closed-loop system by using the Nyquist plot when K=1. Also check the result using the Matlab command 'roots'
N=2이고 P=0, Z=N+P이므로 Z값은 2 => Unstable
2. For the following block-diagram, perform the given problems using th Matlab.
1) Determine th closed-loop stability using the Nyquist plot.
K=1 일때
N=0이고 P=0, Z=N+P이므로 Z=0 => stable
K = 2 일때
N=2 이고 P=0, Z=N+P이므로 Z=2 => unstable
K = 5 일때
N=4, P=0, Z=N+P이므로 Z=4 => unstable
2) Depict the unit-step response for eack K.
K = 1 일때
K=2 일때
K=5 일 때
