My professor gave the class an extra credit problem to try and make up for the low test average (less than 50%) from our first exam.
The problem is a root locus design. The Gp(s) = 1/s(s^2+4s+5). He gave an example using a PI compensator, in which he used a K value of 3, resulting in:
Overshoot:38.36%
Tp=4.55
Ts= 9.04
He wants us to get a settling time, Ts, less than 5 seconds. However, this seems to be impossible. The only thing that I thought might work is using PID instead of PI. However, we were not taught this in class, nor r we going to be tested on it. I have tryed but failed, getting my best result of Ts=5.37 seconds using a k value of 4.9.
Please Help!
