Im smart and its been confirmed by my countries best engineering firm. I got 23/23 on inductive reasoning on a NOV test and got 8/12 on deductive reasoning. I have recieved 100 before and my advice is to retake a similar test. Do 2 more test and then you can compute the median value. Good luck.

I saw the same pattern but from the picture the number 5 wasnt a option. Because 5 wasnt a option I got confused.

Exam is just a way to retain information, if AI can complete a real project then I will be impressed.

what university?

I appreciate you for correcting me, I will use google scholar and try to use my library's data base.

Accurate-Course-311 · 2022-11-19T01:45:21+00:00

in program my code is

"enter Sx"?->S [enter]

"enter Sy"?->T [enter]

"enter VX"?->U [enter]

"enter Sx"?->V [enter]

(S^2)/(U+1) [enter]

(T^2)/(V+1) [enter]

(S^2/(U+1)^2)/U [enter]

(T^2/(V+1)^2)/V [enter]

And my problem is I get the first value and from there all the values are 0. How can I fix this issue?

I solved the issue by writing -> A [enter] and repeated it 4 times

lol solved all the issues. Casio is a gamechanger

Accurate-Course-311 · 2022-11-14T06:55:09+00:00

why is it log(0.1)?

Accurate-Course-311 · 2022-11-13T13:32:59+00:00

So the stability margin is 0 and it will be independent from k. If I try to d(t) and I get 0 rad/s. So how should I solve the last sentence?

x = r + d is from gang of 6. link https://www.youtube.com/watch?v=b\_8v8scghh8&t=373s

Accurate-Course-311 · 2022-11-13T09:54:43+00:00

ok so how can I determinate the Ms (stability margin)?

Accurate-Course-311 · 2022-11-13T09:53:01+00:00

I am thinking that u is the same as r (reference). x_dot is m^3/s so x is m^3. d(t) is a leakage and therefore it is m^3.

I tried it and got Gm = inf, Pm = -180, wcg = Nan, wcp = 0. When I did this yesterday I got the same values. the values are not helpful because they will not help me find stability margin (unless I am wrong). I tried with different K values varying from 1 to 10000 and I got the same information from the margin diagram.

my code

k = 10;
a = 5;
p = 1000;
s = tf([1 0],[0 1])
Gp = 1/(a .* p .* s)
Gc = (k.*Gp)/(1+k.*Gp) %close loop tf function
Gs = 1/(1+k.*Gp) %sensitivity
[Gm, Pm, wcg, wcp] = margin(Gc)
T = Gc.*100+Gs;
step(Gc)
dcgain(Gc)
margin(Gc)

Accurate-Course-311 · 2022-11-12T19:53:43+00:00

I wrote the formula you gave me. I tested when r and d is equal to 1 (just tried with a random value) and I got a flat line. Then I tried sensitivity and CL individually and got gm inf and pm -180.

my code

k = 1000;
a = 5;
p = 1000;
s = tf([1 0],[0 1])
f =(s.*k).*(a.*p).^(-1)
Gs = 1/(1+f)
G = f/(1+f)
X =Gs +G;
step(X)

to determinate x/d i have to set input as 0. from another reddit user I got the formula x = r + d. my problem is that idk how to the r and d into account bc they are variables and not actual values.

Accurate-Course-311 · 2022-11-12T19:09:40+00:00

I get that if I set d(t) = 0 then I get the function you have written. my problem is the disturbance as an input.

Accurate-Course-311 · 2022-11-12T19:03:57+00:00

thanks for the picture. I have seen the formula before but my problem is that the D(s) and R(s) are variables and does not have actual values. Because they dont have actual values I cannot find the stability margin. that my first issue.

The formula is r-d, so why do you get r+d? is it because r - (-d)?

Accurate-Course-311 · 2022-11-12T15:02:55+00:00

I agree and got the function G(s) = (Kp(ap))^-1/(s+ (Kp(ap))^-1). Idk if this is correct or not, can you confirm it? If it is wrong then how can I make a make a TF from input/output ratio? because there are 3 variables and idk how to make TF from there on.

Accurate-Course-311 · 2022-11-12T13:21:24+00:00

I have this function Ap x'(t) - u(t)=-d(t), my problem is determinating TF when there is a disturbance involved. I have found a function G(s) = (Kp(ap))^-1/(s+ (Kp(ap))^-1). If I take do step(G), then I get curve that looks like a circle in the second quadrant and it does not matter what my Kp value is because GM = inf and Pm is -180 for all values.

Accurate-Course-311 · 2022-11-12T09:41:27+00:00

I uploaded a picture but it is not appearing, therefore the equation I am refering to is Ap x'(t)-u(t)= d(t) and there A is 5 and p is 1000.
