Electronic Implementation of the Mackey-Glass Delayed Model

The celebrated Mackey-Glass model describes the dynamics of physiological $\mathit{\text{delayed}}$ systems in which the actual evolution depends on the values of the variables at some $\mathit{\text{previous}}$ times. This kind of systems are usually expressed by delayed differential equations which turn out to be infinite-dimensional. In this contribution, an electronic implementation mimicking the Mackey-Glass model is proposed. New approaches for both the nonlinear function and the delay block are made. Explicit equations for the actual evolution of the implementation are derived. Simulations of the original equation, the circuit equation, and experimental data show great concordance.
