Fractional Order Modeling and Identification for Electrochemical Nano-biochip
Résumé
This chapter deals with fractional order modeling and identification for electro-chemical nano-biochip. A generalized gray-box fractional order model is proposed to better describe the dynamical behavior of this type of process. Assuming a priori fixed (possibly estimated) values of the fractional order derivatives and using a discrete-time approximation of the fractional order model, a recursive instrumental variable algorithm was applied to estimate its parameters. The feasability of the proposed approach is illustrated through the identification of a real electrochemical biochip (collaboration with LETI/CEA).
