摘要：
This paper studies the stabilization via observer-based feedback control for fractional-order systems with input delay. Firstly, the system is transformed into an input-delay-free system by using Smith predictor. Then a necessary and sufficient condition for observer-based controller design is presented, based on linear matrix inequalities (LMIs). While, implementation problem of the controller is provided. Finally, a numerical example and a fractional inverted pendulum system example are given to illustrate the effectiveness of the design method. (C) 2019 ISA. Published by Elsevier Ltd.
