  This paper considers the problem of robust stability and stabilization for
linear fractional-order system with nonlinear uncertain parameters, with
fractional order 0<a<2. A dynamic output feedback controller, with
predetermined order, for asymptotically stabilizing such uncertain
fractional-order systems is designed. The derived stabilization conditions are
in LMI form. Simulation results of two numerical examples illustrate that the
proposed sufficient theoretical results are applicable and effective for
tackling robust stabilization problems. Keywords: Fractional-order system,
nonlinear uncertain parameters, linear matrix inequality (LMI), robust
stabilization, dynamic output feedback.
