摘要：
In this work, the synthesis of a full order dynamic output feedback controller (DOFC) for Fractional-Order Systems with a derivative order 1 < alpha < 2 under norm-bounded disturbances is investigated. The designed DOFC must ensure the internal stability of the closed loop system and satisfy a disturbance rejection criterion which quantifies the disturbances effect on the desired output. This kind of problems is referred as H-infinity control. The existence conditions and design of DFOS are given. An LMI-based minimization problem is derived based on the H-infinity-norm computation for fractional order systems. Finally, simulation results are presented to illustrate the performance of the proposed methodology. (C) 2017, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd.
