WebSep 28, 2024 · 1 Answer Sorted by: 3 A system with simple distinct poles on the imaginary axis (and note that the origin is on the imaginary axis) and no poles in the right half-plane is called marginally stable. If you have poles with multiplicity greater than 1 on the imaginary axis, or if there are poles in the right half-plane, then the system is unstable. money heist is in which languageWebExponential stability. In control theory, a continuous linear time-invariant system (LTI) is exponentially stable if and only if the system has eigenvalues (i.e., the poles of input-to-output systems) with strictly negative real parts.
