Discrete Laguerre filters are a simple and efficient tool for approximating stable dynamical systems. They can be used not only to model the system dynamics but also to express the controller structure. In this paper the real-time implementation of a Laguerre network-based control system using a micro programmable logic controller (PLC) is presented. Generally the PC is not needed for the real-time...
Statistical process control (SPC) is an approach to process control that has been widely used in any industrial or non-industrial fields. SPC is based on so called Shewhart's conception of the process variability. This conception distinguishes variability caused by obviously effected common causes from variability caused by abnormal assignable causes. New manufacturing technologies and concepts strongly...
In the paper fuzzy logic controller for rehabilitation robot manipulator is presented. The control object is two degree of freedom robot manipulator. In this case there are two main problems. The first is, that the object is for rehabilitation process so the quality of control system is very important problem. The next problem is with the highly nonlinear dynamics of a robot manipulator. Suggest fuzzy...
In this paper, the manipulator identification process was presented. To identify single-layer neural network with sigmoidal functions that describe individual neurons was used. The main goal was the approximation nonlinearities of manipulator model in real time. It was assumed that the nonlinearity of the manipulator are unknown. The stability of the identification system adopted by the law of the...
The paper deals with several theoretical aspects connected with determination of positioning accuracy of parallel kinematic structures (PKS) with special regard to the Tricept type PKS. The conventional serial structures employ translate or rotational movement (or their combination) and their element are ordered in serial manner. On the other hand, parallel structures comprise a set of telescopic...
The paper describes the design and realization of the mobile application for the Android operating system which is focused on manual control of mobile robot using wireless Bluetooth technology. The application allows the robot control interaction with the display, or voice. When we use a graphical interface, we can monitor the current distance of the robot from obstacles. The measurement of distance...
Significant developments of technology over the last years, especially in pervasive/ubiquitous computing, have made the dream of smart environment technology true. Merging of this technology with mathematical prediction apparatus allowed raising a new level of smart environments - automating the routine control tasks and pro-active interaction. This paper deals with the potential of automation of...
This work solves actual problems of inertial navigation systems - increasing of precision. Main part of the paper deals with determination of accelerometers and gyroscopes calibration constants using a differential evolution algorithm. The determination of constants is based on the difference between trajectory recorded by GPS receiver and trajectory calculated from inertial sensor data. Moreover,...
The paper presents the algorithm of the programmed guidance of the flat track anti-tank missile onto a target, both motionless and moving by means of system called SACLOS (Semi Automatic Command to Line-of-Sight). The adjustment of control is done with the use of the angles between the target line-of-sight and the missile line-of-sight. The proposed algorithm of control enables attacking not only...
Tunnel furnace belongs between thermal devices with big energy consumption. Therefore constructers and users are interested about some possibilities to decrease energy consumption in this group of thermal devices. One way for this aim appears the analysis building or rebuilding tunnel furnace by evaluation by simulation cases. In paper will be described mathematical model of tunnel furnace as basic...
KPIs (Key Performance Indicators-KPIs) are quantifiable values that reflect the critical success factors of operation, enterprise companies. Choice of these parameters depends on the type of system being examined. As an example of the technological process in finding the optimal mode, KPI respectively, is a process of rock disintegration. The theoretical basis is the energy of disintegration theory,...
The following article proposes fuzzy tool for processing risk analysis in the area of information security. The paper reviews today's approaches (qualitative and quantitative methodologies) and together with already published results proposes a fuzzy tool to support our novel approach. In this paper the fuzzy tool itself is proposed and also every main part of this tool is described. The proposed...
The performance portrait based optimal controller tuning may be considered as a generalization of the well known method by Ziegler and Nichols [1] that integrated an experimental plant identification with the controller tuning. Up to now, the performance portrait method (PPM) has been presented as a tool for robust and optimal controller tuning [4]–[6]. This paper presents its application as a new...

In the next part selected simulation software is presented, which is used to handle the issue. Furthermore the input...
This paper proposes a design approach of a simple algorithm detection system based on evaluating of LQ control performance index values, that is applicable on nonlinear dynamical systems described by Takagi-Sugeno model. The same approach has been used for linear dynamical system, however the question was, whether this method could be modified and applied in nonlinear system. Arbitrary state space...
A robot needs to have a representation of the environment to free of collision move. There are different types of environment maps in mobile robotics. The most used ones are metric maps. The aim of this paper is the proposal of algorithms for real robotic system that can map the environment. In this paper we deal with the analysis of properties of the laser scanner and the making of its model. Further...

In the article a new approach for optimal control of the multistage differential-algebraic systems was presented. A merit function based on Fletcher's augmented Lagrangian was used. The necessary optimality conditions for the optimal control of multistage index-1 DAE systems were stated and locally optimal solution was obtained using the inexact Newton method. The only constraints for decision variables...
An article presents simulation study results of a piezoelectric generator, which can be used for supplying power to wireless sensor nets in the parameters monitoring systems of structure. In many technology branches, parameter monitoring of structures is necessary to guarantee a non-failure operation of technical applications.
