H-1 day

so..............


thank God it's monday.


tomorrow will be my first exam, BG3002 Control in Biosystems


well...
what do i suppose to say?

i haven't understand Poh's last part: how to plot a Nyquist plot...
how is it?

first.............. i have to separate the real and imaginary part.
then, make the formula for |H(jw)| <<< that's the magnitude of the OPEN-LOOP TS.
then, make the formula for < H(jw) = -tan-1 (im/re) <<< that's the direction

then, plotting them on the im-real axis; with w (omega) from 0 to infinity.

also have some difficulties with relative stability

relative stability... the phase and gain **** (damn, i even forgot the term of it...)


ok... let us start again.
from the Nyquist part...


i have to understand!!!



TARGET = B-
