Abstract :
This paper provides sufficient conditions for robust stability of a multivariable interval feedback system. The result is based on the robustness of the well known diagonal dominance of the system return difference matrix, which allows for a simple application of the Nyquist criterion to a multi-input/multi-output (MIMO) system
