Dual-Source Bumpless Transfer Control for Switched Linear Systems

This paper establishes a framework of dual-source bumpless transfer control for switched linear systems. A new performance called integral bumpless transfer performance is introduced to measure the distance between the real control signal and the reference control signal over the whole time domain. Moreover, the classical switching-related bumpless transfer performance to suppress the bumps of the control signal at switching points is simultaneously considered. Thus, the dual-source bumpless transfer control problem is formed, aiming at achieving stability while preserving both bumpless transfer performances. A sufficient condition for asymptotic stability with dual-source bumpless transfer performance is developed with the controller and switching law designed. Finally, through the railway system model, the feasibility and the superiority of the proposed dual-source bumpless transfer control strategy are illustrated.
