Abstract In this paper presents adaptive hybrid control algorithm for the underactuated system, called Schmid pendulum. Static pendulum support was replaced by the wheeled platform to demonstrate advantages of proposed approach. The control task is output stabilization of the pendulum upright equilibrium in an uncertain plant parameters, limited control and unknown friction presence. In contrast to known approaches, real-time controller adjustment without any preliminary identification procedures has been provided. Obtained algorithm has been successfully verified via experimental implementation on the real mechatronic setup.

This paper presents the results obtained by visual predictive control laws in real-time visual servoing architectures. A key role when designing a stable image based control law is played by the visual features, and thus both points and image moments were considered and their performance revealed. A 6 d.o.f manipulator robot with an eye-in-configuration is used to design a visual servoing architecture and realtime implementation using Matlab is described. The results of different experiments for planar static objects are presented and discussed. For establishing the performance of visual predictive control laws a comparison with classical image based control laws is conducted.

In this paper, we develop a computational framework for fully automatic deployment of a team of unicycles from a global specification given as an LTL formula over some regions of interest. Our hierarchical approach consists of four steps: (i) the construction of finite abstractions for the motions of each robot, (ii) the parallel composition of the abstractions, (iii) the generation of a satisfying motion of the team;(iv) mapping this motion to individual robot control and communication strategies. The main result of the paper is an algorithm to reduce the amount of inter-robot communication during the fourth step of the procedure.

This paper deals with the output stabilization of time-delay systems with sector-bounded nonlinearity. In this paper we will consider the problem of absolute stability for a class of time-delay systems which can be represented as a feedback connection of a linear dynamical system with unknown parameters and a uncertain nonlinearity satisfying a sector constraint. For a class of output control algorithms a controller providing output exponential stability of equilibrium position is proposed.

The aim of this work is to create application for mobile devices such as PDAs running under Windows Mobile. With this application, and PDA it will be able to process the analog data measured by the A / D converter and display it in graphs. Use of the converter has four analog inputs. These are converted into digital form and transmitted via the communication interface Ethernet to WiFi router. Application running on a PDA uses WiFi connection to download measured data and to processes them. The advantage of this solution is particularly small size and mobility of the PDA. This eliminates the need to transfer the measuring device. This makes a possibility of usage wide especially in the manufacturing industry in the halls where it should be measured in several places at the same time, and the values compared between each other.

In this paper a new approach for cancellation of a multiharmonic disturbance is proposed. Compared with a number of known results in this paper the disturbance compensation problem is solved when the output variable is measured only, a relative degree of the plant is arbitrary and the control channel has the constant time delay. The numerical example is presented to illustrate theoretical result and the reaction wheel pendulum on a movable platform is considered as the plant to demonstrate that proposed approach is realizable and can be plugged in practice. Created by hand disturbance moves the platform in horizontal surface and the pendulum is oscillating. The second goal of this work is the development of mechatronic applications using in education.
