Closed loop poles vs open loop poles

WebIf the open-loop system has \(P\) unstable poles, the closed-loop system is stable if and only if the Nyquist plot encircles \(–1\) point \(P\) times counterclockwise. If the Nyquist plot passes through \(-1\), then the system has a closed-loop pole on the imaginary axis (critically stable). WebIf we decrease the loop gain sufficiently, we can move the closed-loop poles further into the left-half plane and we can change the performance of our system. This can be accomplished graphically by "grabbing" the pink boxes marking the closed-loop pole locations and dragging them toward the open-loop pole locations (marked by x 's).
