The application for GPS devices expand the use of GPS devices. It is very simply designed and has intuitive operation and environment. The big advantage is an on-line access to the application. The basic characteristic of similar applications is planning and rendering the route which was taken. Therefore, this application provides both of these functions. Route from point A to point B might be planned...
This paper deals with the parameters identification of heater model, which is a part of the laboratory object Armfield PCT40. Dynamical behavior of the heater is described by delay differential equation and equation parameters are obtained via classical identification technique implemented in Matlab Identification Toolbox and also with using a graphical method in time domain. The obtained models can...
The paper describes the typical area of specific research of our department and that is the software implementation for support the monitoring and control of technological processes. It presents a modern robust software was created to support control and monitoring of the experimental models have been developed within the multiunivesity project GACR in recent years and successfully used in the teaching...
This report presents a selection of exploitation problems which can be effectively solved by water network modellers. It includes a list of worldwide-available software dedicated to modeling water distribution systems. This type of software can serve as the key tool supporting management and water pipe networks' control. Based on a few samples of real-life problems this report points out recent functionalities...
The paper discusses relations between so called Interpretation Space (IS), Sign Model (SM) and their Connection. The principal importance has the process of the Interpretation that assigns the semantic contents (in IS) to signs and sign formation (from SM). The fact that the interpretation mapping from lower to higher level of IS is non constructible induces the situation of „bottom-up emergence”...
A dynamic model of the system consisting of four ON/OFF solenoid valves and two pneumatic artificial muscles in antagonistic connection (PAM based actuator) was designed. This model regards with different dynamic characteristics of the pneumatic artificial muscle by inflation and deflation of compressed air into or from muscle. The model was created in Matlab's Simulink environment.
Object tracking is a problem of obtaining usually positional and motional information about the object. The observation is usually in the form of a picture, radar or sonar image. A key element of the tracking problem is to estimate a (non-measurable) state of a stochastic system based on corrupted measurements. This problem is well treated in literature. If the objective is tracking multiple objects...
Kinematic analysis of a semi-rigid-elastic multi-body torsional vibration model of gears system is studied by using the state-space model. Equation of motion of gears system is obtained. A four-degree-of-freedom model of the pinion gear-wheel gear system is considered for simplicity. The pinion gear body and wheel gear body are assumed to be rigid. The teeth are assumed to be elastic and parallel...
The paper describes a way of control of a serial mechatronic chain (electric servodrive + gearbox + cam mechanism + load) in the sense of SW tools usage. The goal of the control law is to reach the maximum position accuracy. The driving motor is set in the position mode which allows a definition of the displacement law (table of predefined position values). The control law uses position-speed-torque...
The subject of this paper is the analysis of properties of the mechatronic chain. That chain was represented by the mechanical system where the particular mechanical elements were linked in serial satisfying this setup: electric servomotor — mechanical gearbox — cam — load. The mechanical and the electrical parameters were monitored. The current and the voltage sensors were installed to determine...
In the paper we demonstrate use of the computer modeling as a tool for study of the real technological processes. For this purpose, we present the software application that we programmed for study of the soaking which belongs to tannery operations of the raw hide treatment. The software application is destined for computing of the concentration field of unbound undesirable component removing from...
This paper deals with the use of computer simulation with the aim of design efficient production in manufacturing and production systems. In our case, the possibilities of such use are demonstrated on particular example from industrial practice. The purpose was to build up a model of the prepared manufacture system and, especially, to propose a solution designed to increase productivity and to find...
We present the PI/PID controller settings for the first order systems with dead time, based on the modulus optimum criterion. The settings provide fast closed-loop response to changes of the reference input. Unlike most other tuning methods, the parameters are obtained without approximation of the delay term, so they remain valid for long dead time. Besides the performance indices, quality of the...
The paper deals with fault tolerant information systems in raw material industry. Database is a heart of every information (control) system. To store the system in the category of fault tolerant (or disaster tolerant) systems, the goal is to solve the database continuity. Current database systems offer technology for online data mirroring. The paper brings details about solution of database mirroring...
This contribution deals with small real-time operating system RTMON developed at our institute as a teaching aid for microcontroller programming lessons. This new system is based on previous versions of RTMON for HC11 microcontroller and for PC. It should make it possible for students to understand the basic concepts of creating applications with use of operating system and easily write their own...
This paper describes experiment based on calculation of heat consumption for part of the town during the winter season. It is based on historical data analysis in the view of the nature of the sun activity. The relationship between heat consumption and outside temperature is sought and expressed in linear formulas. These relations are then improved by the inclusion of the information about sun activity...
Real objects in general are fractional-order systems, although in some types of systems the order is very close to an integer order. Since major advances have been made in this area in the last decades, it is possible to consider also the real order of the dynamical systems by using fractional order of the differential equations. Such models are more adequate for the description of dynamical systems...

In flow control and in hydraulic systems used in automotive industry, e.g. brakes or automatic transmission units, one of the basic controlling problems is the precise adjustment of oil (fluid) pressure. As an electromechanical actuator, switching and linear variable solenoids are widely used in such applications. In this paper, a magnetic valve is analyzed in details. The main features of the system...
