Hello,
Could someone explain how I can get the pole positions from given system requirements? I need to regulate
a fourth order, inherently unstable astatic system given by the identified OL tansfer function:
\(G_{OL}(s) = \frac{148}{0.6s^4 + 14.8s^3 + 408s^2 + 642s}\)
using a PD or lead regulator (nothing else works). The system requirements are roughly 10% OS and a settling time of less than about 4 or 5 seconds. I know how to find the compensator coefficients once I have the required pole locations but question is how do I find the pole locations? I know how to do it for a second order system , but not for a 4th order system.
