I have some questions about theory of stability:
- Can a system be stable and have poles in the right semiplane of s plane?
- If a system has poles in the right semiplane, what should happen in GH plane to be stable?
- Stability criteria can be applied to systems with H(s)<>1 (<> = distinct)? or its necessary do some transformation in this case?
If someone can help me with this I'll be grateful!
