Robust Gamma-Stability Analysis in Plant Parameter Space

Abstract

Given a characteristic polynomial whose coefficients depend polynomially on l uncertain parameters, the following robustness problem arises: Determine whether all the roots of the polynomial are located in a prescribed region Gamma in the complex plane for all admissible parameter values. Mapping the boundary of Gamma into the parameter space. Testing this condition graphically etc. and applying the method to a track-guided bus with uncertain mass and velocity.
