A Stability Robustness Test for Systems with Linear Time-varying Uncertainties

In this paper, a novel stability robustness test for systems with linear time-varying uncertainties is introduced. The advantages of the stability robustness test lie in the fact that it can cope with multi-input multi-output, stable, or unstable systems whose linear time-varying uncertainties can be represented by a standard structured uncertainty model, and that the implementation of the test is straightforward. The tool used to provide the means of determining system stability robustness is the linear time-invariant ν-gap metric.
