Control of the weakly damped System with the embedded system support
This paper deals with the experimental verification of the importance of embedded systems with an applied MEMS sensor in controlling weakly damped systems. The aim is to suppress actively residual oscillations. The model of a planar physical pendulum with a prismatic joint was chosen for the experiment. The sensor made by MEMS technology, in which three-axis gyroscope and three-axis accelerometer are integrated, has been used for sensing the angle of deflection of the load from the equilibrium position. The simulation model represents the crane arm with a moving carriag
Wireless (power transfer) transmission of electrical energy (electricity) intended for consumer purposes up to 50 W
This project deals with Power Semiconductor Systems PSS for wireless transmission of electricity to the power of 50~W with regard to the distance and transmission efficiency. We decided to use electromagnetic resonance for electrical energy transmission. For experimental verification, we have wound two coils of identical dimensions. At a given power transmission solutions, we obtain the highest efficiency η = 70% at a distance of 5 cm, where the transmitted power was 48
Simulation of heat transfer and electromagnetic fields of protected microcomputers
The paper presents results of collaboration between Department of mechatronics and electronics at University
of Žilina and VÚVT Engineering a.s. Žilina in area of heat transfer simulations and disturbing electromagnetic radiation
simulations in computer construction. The simulations results were used in development of protected microcomputer
prototypes in frame of applied research at both of workplaces
Protected microcomputers from VÚVT-Engineering
The paper presents properties of new protected microcomputer prototypes that recently developed VÚVTEngineering
a.s. Žilina. The five new prototypes of protected microcomputers and displays provide users with important
protection against radiated information leaking from a computer and suppress unfavorable effects of electromagnetic
radiation on a man. The first part of contribution describes technical parameters of protected microcomputers and displays.
The results of optical characteristics measurement and measurement of electric field radiation from the protected
microcomputers are discussed in the second part of the contribution
