Chapter
The article deals with the description and utilization of a biaxial mechanical educational system for familiarization of observation and weapons systems control techniques. Its application in education is divided into three sections. The first part deals with the model design and kinematic/dynamic analysis of the whole mechanical structure. A mathe...
Article
When designing a mechatronic system, several steps are taken into account. One of the main steps is the design of a CAD model representing the physical part of the system, and another major point is the development of the mathematical model necessary for the respective controller design. This paper combines both design steps and shows the advantage...

Variations of un-maned vehicles or drones are widely used in diverse fields, including monitoring or manipulation with dangerous substances. One of the best drone construction, which can be used in these fields is an X-copter. This paper serves as an introduction to basics of quadcopter anatomy and advice to choose components based on their propert...

The paper presents a basic description and examples of the use of so called descriptive functions, allowing analysing the influence of inherent and indispensable components of all mechatronic systems mechanical subsystems - so called hard nonlinearities. These parts “causing” - in addition to the centrifugal and Coriolis generalized forces- the non...
Article
Full-text available
At many motion control tasks, the problem of oscillations existence in multidimensional system with limited motion control and imperfect or complicated state quantities measurement possibility exists. Paper describes active damping simple possibility of these type systems and by two-dimensional system physical model shows active damping possibility...

The expanding capabilities of today’s microcontrollers and other devices lead to an increased utilization of these technologies in diverse fields. The automation and issue of remote control of moving objects belong to these fields. In this project, a microcontroller Raspberry Pi 2B was chosen for controlling DC motors and servo-motors. This paper p...
Article
Nowadays technology enables using of small devices to control complex systems. These devices (microcontrollers) can provide enough performance to substitute personal computers (PC). The two most known microcontrollers (Arduino and Raspberry) are connected together to one system. The article provides insight into the issue of inputs and outputs and...
Article
Article deals with physical models of mathematical and simple and double physical pendulum for its stabilization possibilities verification in instable inverse position. Whereas classical stabilization by proximal joint horizontal movement of inverse mathematical pendulum is well known and in article is just why and when is possible, the case of st...
Article
The contribution serves as a preview of the OFDM modulation signal, which is used in cellular and other wireless networks. We look closer on this problem and we are subsequently discussed general topics. That include an issue of mobile networks in their general concept and also more insight on the network 4 and 5 generations. Within the network 4 g...
Article
The contribution describes the basic principles of measurement and the use of global positioning systems, focusing on the most widely used system NAVSTAR, including used protocols. It deals NMEA protocols-which today ranks among the most widespread GPS system, RINEX-which is an interpretation of "raw" data, these systems, and RTCM-which is an alter...

Full-text available
Text deals with 6 degree of freedom measuring robot kinematics description enabling manipulation with measuring effector in 3D space. Mentioned description flowing from Denavit- Hartenberg notation for serial ordering of ideally stiff bodies connected by kinematic pairs, makes possible to create complete set of transformation matrices for coordinat...
Chapter
The available control synthesis methods, as well as the synthesis software tools, however sophisticated, are capable of dealing only with rather simple controlled system models, mostly linear. In practice, however, the systems tend to be complex, nonlinear, and subject to many constraints. In addition, the characteristics of the system components m...
Article
The paper deals with development and solution of computer model of current type converter with load reactive energy compensation. In detail, it solves a dynamic-state of the system: non-controlled rectifier - dc link - current inverter - compensation rectifier - load. Two qualitatively different methods of solving have been used. The system lineari...
Article
The article investigates the properties of an induction motor supplied by a voltage with higher harmonics. The corresponding computer program allows investigating the properties of the motor for different combinations of input data in steady and transient operation.
