Conclusion The system is stable only when all the closed loop poles are located in the left-hand half of the s complex plane ap) The system become unstable as soon as one closed-loop pole is located in the right-hand half of the s complex plane (rhp) Stable UnstableConclusion • The system is stable only when all the closedloop poles are located in the left-hand half of the s complex plane (LHP); • The system become unstable as soon as one closed-loop pole is located in the right-hand half of the s complex plane (RHP)
