Abstract :
The systematic approaches based on LFT and sensitivity theory to analyze the stability performance of multi-machine system with parameter uncertainties is proposed. μ analysis is developed to solve the stability boundary. The method proposed in this work is not only useful for analyzing the systems with structured uncertainties, but also applicable to the controller design and robust controller evaluation with perturbations taken into account.
