The main aim of proposed article is the design of new software system for modelling and control of discrete‐event and hybrid systems using Arduino and similar microcontrollers. In this paper we propose a new tool. It is based on Petri nets and it is called PN2ARDUINO. It offers a capability of communication with the microcontroller. Communication with the microcontroller is based on modified Firmata...
To ensure reliable execution of flight tasks in the presence of both external perturbations and internal parametric perturbations, deterioration of the characteristics of the sensors, a control system structure based on intelligent technologies is proposed. The process of forming a “knowledge base” of a fuzzy controller is considered. The results of mathematical modeling of the longitudinal UAV control...
The main aim of this paper is to present the study designed to check whether negative attitudes towards interactions with robots may be influenced by demonstrating videos presenting advanced modern robots. The attitude was measured with the use of the Negative Attitude toward Interactions with Robots questionnaire (NATIR). 66 subjects participated in the study divided into the pretest, a video presentation...
The Internet of Things (IoT) and mixed reality are now among the most important areas in research or in practice. The aim of this paper is to propose an appropri‐ ate way of connection of these two areas, where is pos‐ sible to control and monitor mechatronic devices using a mobile device with augmented/mixed reality support. The main task will be to explore these options in the area and implement...
Interactive 3D visualization technology has brought many benefits into education. Since it is possible to visualize behavior of wide range of devices, it is much easier to imagine processes where these devices are included. The paper demonstrates the application for interactive teaching of control theory. It allows to simulate a holographic model of a selected mechatronic system that is a digital...
The use of Multi Agents Systems (MAS), Cloud Computing (CC) and Fuzzy Inference System (FIS) in e-commerce has increased in recent years. The purpose of these systems is to enable users of electronic markets to make transactions in the best conditions and to help them in their decisions. The design and implementation is often characterized by the constant manipulation of information, many of which...
Cloud environments made up of a large number of compute and storage servers provide ondemand services in a usage-based consumption model (pay-as-you-go). Load balancing is one of the major problems in the cloud. Indeed, the dynamics of demand requirements and QoS, as well as the variability of cloud resources and its provisioning models make difficult the operation of performance evaluation of the...
The digital revolution has encouraged many companies to set up new strategic and operational mechanisms to supervise the flow of information published about them on the Web. Press coverage analysis is a part of sentiment analysis that allows companies to discover the opinion of the media concerning their activities, products and services. It is an important research area, since it involves the opinion...
In recent decades, the airline industry has become very competitive. With the advent of large aircraft in service, unit load devices (ULD) have become an essential ele‐ ment for efficient air transport. They can load a large amount of baggage, cargo or mail using only one unit. Since this results in fewer units to load, saving time and efforts of ground crews and helping to avoid delayed flig‐ hts...
This paper deals with a possible approach to controlling marine fish stocks using the prey‐predator model described by the Lotka‐Volterra equations. The control strategy is conceived using the sliding mode control (SMC) approach which, based on the Lyapunov theorem, offers the possibility to track desired functions, thus guaranteeing the stability of the controlled system. One of the most important...
