Zusammenfassung:	This paper presents a robust control strategy for uninterruptible power systems (UPS) based on the linear matrix inequality (LMI) framework. Taking into account the average model of the UPS, a state feedback controller is proposed that assures the local stability of the closed-loop system for all admissible load variation while minimizing an upper-bound on the 2-norm of the input-to-output operator. A real-life example is used to demonstrate the approach.
