Generation of complex phenomena in a simple electromechanical system using the feedback control

In this Letter, a feedback control method is proposed for generation of some interesting complex behaviors in electromechanical devices. The controllers for linear electromechanical systems based on the Power Supply Feedback Control are designed and their mathematical models are obtained. Computer simulations of the controlled systems show complex dynamical behaviors such as jump phenomenon, Sommerfeld effect, period-nT and chaotic oscillations.

► We present a feedback control method based on Power Supply Control. ► Two controllers are designed and applied on a simple electromechanical device. ► Computer simulations of the controlled systems show complex dynamical behaviors. ► The controlled device can be used as a home sieve, liquid mixer or eggbeater.
