PDF-Nyquist for open-loop unstable systems !!Relative stability (gain marg

is equal to the number of openloop poles in the righthalf plane The closedloop system which is openloop stable no openloop poles in RHP is stable if and only if there are no encirclements of. Mapping If we take a complex number on the splane and substitute into a function an other complex number results eg substitut ing 4 3 into 2 1 yields 16 30 Contour Consider a collection of points called a contour A Contour A can be mapped Lect.6 Stability.
