The Routh–Hurwitz stability criterion is a mathematical test used in control theory to determine the stability of a linear time-invariant (LTI) system based on the coefficients of its characteristic polynomial. Specifically, it helps assess whether all poles of the system's transfer function have negative real parts, which is a necessary condition for the system to be stable.
