A variety of nonlinear dynamic responses for a new electro-vibro-impact system is presented, with indication of chaotic behavior. By mathematical modeling of the physical system, an insight is obtained to the global system dynamics. The modeling has established a good correlation with experimental data, and hence can be used as a numerical tool to optimize the system dynamics. In particular, with respect to impact forces and progression rate, may then be achieved with minimal computational cost.

A method to extract energy from an excitation which is stochastic in nature is presented. The experimental rig comprises a pendulum, and a vertical excitation is provided by a solenoid. The control input assumed in the form of a direct current motor, and another motor, used in reverse, acts as a generator. The stochastic excitation has been achieved by varying the time interval between switching the RLC circuit on and off according to a random distribution. Such non-linear vertical excitations act on an oscillatory system from which a pendulum is pivoted. The Pierson-Moskowitz spectrum has been chosen as the random distribution while an inverse transform technique has been used for generation of the random excitation signal in LabVIEW environment. Moreover, a bang-bang control algorithm has been implemented to facilitate rotational motion of the pendulum. Experimental observations have been made for various noise levels of vertical excitations, and their implication on energy generation has been discussed. A positive amount of energy has been extracted for a minimal amount of the control input.

“…The pressure valve is the moving coil type actuator. The response of the moving coil type actuator is faster because of the light weight [1][2][3][4][5]. The low cost of the AVR microcontrollers using the linear digital controller was designed to control the pressure control solenoid, and the superiority of the proposed controller was confirmed experimentally.…”

This paper describes the advanced control of solenoid for pressure valve for electric pressure cooker. To remove the problem of the on/off non-proportional pressure control method which was used to control the existing solenoid, newly redesigned solenoid was adopted and the advanced control method, linear proportional control method, was proposed. The control system by the pressure sensor and AVR was manufactured and its validation was proved through the experiment.
