Realizations of mathematical model of wind turbulations as lumped electronic circuits
Bürger, David ; Šotner, Roman (referee) ; Petržela, Jiří (advisor)
This semester work deals with implementation of the mathematical model known as modified Lorenz system as an electronic circuit with lumped parameters. Dynamical system is autonomous, deterministic and is described by a set of first-order ordinary differential equations. Our aim is to derive three different circuitry realizations each having specific properties. In the first case realization is canonical in the sense of the integrator block conception where the internal system parameters are adjusted by three potentiometers. Second realization represents modification towards independent adjustment of all four system parameters and, consequently, to tracing dynamical evolution of model solution. Last oscillator, on the contrary to previous circuits, work in current mode rather than voltage regime.
