We consider a statistical decision problem as a tool for solving control problems with a camera in the loop. The first stage is features extraction from images. Its role is to process images in order to extract features relevant for the control problem. Then, they are fed as inputs to the Bayesian decision problem. At the second stage a loss function, which is a sum of squared deviations of decisions from true decisions is considered. Finally, an approximation of the optimal decision rule is proposed, using a learning sequence of decisions, which - together with feature extracting algorithms - form the controlsystem. The proposed approach is illustrated by a system that is dedicated to control natural gas burners.
In this paper, the spacecraft formation control and its stability problems are studied on the basis of the energy concept. The formation systems are viewed as a multi-mass point system with both generalized elastic de...

In modern industry a real-time Ethernet-based controlsystems are typically used instead of a centralized solution. This is due to the economical reason and to allow easy expansion and modernization of the machines. The distributed architecture enables i.a. the use of hardware emulators instead of the real control object, in a manner transparent to the whole system. This is an advantage because it can be useful for the development of the controlsystem. It will make that cheap and safe testing of complex controlsystems will be available. The testing process might be performed in a working controlsystem in which part of it (e.g. a control object) has been temporarily replaced by an emulator. However, emulators typically need an increased performance of the real-time communication interface to transfer a large amounts of the service data. In this paper we propose a new method to create high performance real-time, Ethernet-based communication solution which will be suitable for the most demanding applications, for example for the development process and connection with hardware emulators.

The paper proposes a framework for incorporating results of the analytical and laboratory measurements directly into the process controlsystem. It is based on an object-oriented framework for cooperative testing of control algorithms implemented for experimental pilot-plants. It enables modification of the control algorithm structure without rewriting the main software component executed on the programmable automation controller (PAC). In this paper the framework is expanded to enable access to web-based services for the purpose of incorporating the results of advanced off-line measurements directly in the process controlsystem.
