Sliding mode control of the Hodgkin-Huxley mathematical model / C. Cavaterra, G. Marinoschi, D. Enachescu. - In: EVOLUTION EQUATIONS AND CONTROL THEORY. - ISSN 2163-2480. - 8:4(2019), pp. 883-902. [10.3934/eect.2019043]
Abstract:
In this paper we deal with a feedback control design for the action potential of a neuronal membrane in relation with the non-linear dynamics of the Hodgkin-Huxley mathematical model. More exactly, by using an external current as a control expressed by a relay graph in the equation of the potential, we aim at forcing it to reach a certain manifold in finite time and to slide on it after that. From the mathematical point of view we solve a system involving a parabolic differential inclusion and three nonlinear differential equations via an approximating technique and a fixed point result. The existence of the sliding mode and the determination of the time at which the potential reaches the prescribed manifold are proved by a maximum principle argument. Numerical simulations are presented.
