Robust regulation of metro lines using time-variant control law

Abstract

This paper presents a new formulation for robust traffic regulation of metro lines. The approach uses a linear time-variant state feedback control law computed in real-time. The formulation is based on the stability analysis using the eigenvalues of the feedback system and consider the traffic model uncertainties and the constraints on its state and control variables. It is assumed the constraints on model variables and uncertain parameter domain defined by convex compact polyhedra. The simplicity and computational efficiency of this formulation makes it applicable to real-time regulation of nowadays metro lines and presents better performance than the obtained using already known robust regulation approaches. © 2003 IFAC.
