Interval and robust stability of two-parameter discrete systems with interval coefficients
И. В. Гайшун, V. V. Goryachkin · Differential Equations · 2015
For a two-parameter discrete system with interval coefficients, we obtain conditions for robust stability and stability in the sense of interval analysis. In the general case, these two notions of stability are distinct; however, they are equivalent under the assumption that the coefficients of the system are nonnegative.
