That is the problem. I have tried that before but it generates the following error:
"??? Cell contents reference from a non-cell array object."
Do you have any resolution to the above error?
i understand that the "nyquist" command in matlab requires one to key in the transfer function..
however, i am stuck here as i am unable to form a transfer function from the following numerator and denominator:
num = s-3/2-1/2*(-24*s+1)^(1/2)
den = 1.25*s^2 +3.75*s + 2.5
i know that...
A separately excited DC motor with 220V, 970rpm, 100A and Ra=0.05ohms. It is braked by plugging from an initial speed of 1000rpm.
I need to calculate i)the resistance to be placed in the armature circuit to limit braking current to twice the full load value, ii)the...
sorry i don't get you. do you mean shift the disturbance D(s) to the left of G1(s) as in in the block diagram?
or do you mean the equation Y(s) - G2(s)D(s) = U(s)G1(s)G2(s)?
please advise. thank you.
U(s) is my input, Y(s) is the output. I have two plants, G1(s) and G2(s). Between these two plants, i have a disturbance input, D(s).
Am i right to say Y(s) = U(s)G1(s)G2(s) + G2(s)D(s)?
If that is the case, how can i get the overall transfer function Y(s)/U(s)? Please advise. Thank you.
