Understanding the motor equation
This is not for school Home work.. I'm a hobbyist, I try to work/understand different concepts... and not for profit too.... coming to the point, yes you are right, the equations is representing the steady state operation where the stator current vector is in phase with rotor Q axis, but still...- nauduri

Understanding the motor equation
Hello, I was going through a technical paper for understanding the PMSM modeling, in that the author has given below equation http://files.engineering.com/getfile.aspx?folder=fb4d57ad-4300-4a4e-982b-b4ab4c635d1a&file=DQ_eq.png where P is a differential operator and Wr is rotor speed in...- nauduri

understanding the system modeling
I have one more thought, can I make the I and D gains of my PID control to zero and make Kp = 1, now by looking at the out put Y(s) with respect to r(s) with this can I get the transfer function of F(s) shown in the below figure...- nauduri

understanding the system modeling
Hello Sir, I have done some googleing and found the below papers 1) http://www.ualberta.ca/~slshah/public_share/IDfromStep_ReviewFormat.pdf 2) http://arrow.dit.ie/cgi/viewcontent.cgi?article=1144&context=engscheleart 3) http://www.mii.lt/informatica/pdf/INFO282.pdf I feel the paper 1 and 2...- nauduri

understanding the system modeling
Thank you sir for your inputs; I'm understanding what ur trying to explain, you are right R is step input and y is the output from picture 4 which I have the transfer function F(S) and need to get G(S)by understanding the concept of "closed-loop system identification" for me to model in...- nauduri

understanding the system modeling
Hello, This is sundaram, I'm working on a speed control of belt driven drum project and I'm new to control system concepts. I'm trying to find the transfer function of the system so that I can model it in simulink and tune the PID and look in to other aspects of the system. The blocks and...- nauduri
