Abstract
dc.description.abstract
Adaptive and non-adaptive minimal realization (MR) fractional order observers (FOO) for
linear time-invariant systems (LTIS) of a possibly different derivation order (mixed order observers,
MOO) are studied in this paper. Conditions on the convergence and robustness are provided using
a general framework which allows observing systems defined with any type of fractional order
derivative (FOD). A qualitative discussion is presented to show that the derivation orders of the
observer structure and for the parameter adjustment are relevant degrees of freedom for performance
optimization. A control problem is developed to illustrate the application of the proposed observers.

In this article we are interested in interior regularity results for the solution μ∈∈ C(Ω¯) of the Dirichlet problem {μ=0inΩc,I∈(μ)=f∈inΩ where Ω is a bounded, open set and f∈∈ C(Ω¯) for all є ∈ (0, 1). For some σ ∈ (0, ...
