Liquid mixing enhancement by PLC-based chaotic dynamics implementation

Abstract EN

In this paper, we present a new programmable chaotic circuit based on the dynamical chaotic system introduced by E.

Lorenz.

The design and realization of the model are accomplished by using a programmable logic controller (PLC).

The system can be modeled and realized with a structured texted.

The nonlinear differential equations of Lorenz model are solved numerically.

The generated chaotic signal by using PLC is applied to a single-phase induction motor via a variable frequency drive to create a chaotic perturbation in the experiments of liquid mixing.

Colorization liquid experiments shows that the generated chaotic motion effectively makes an enhancement of the mixing process in the stirred-tank mixer model in our laboratory.
