Various approaches to control aeroelastic wing section with structural nonlinearity emerged in the last years. One of the approaches is based on the Tensor Product (TP) model transformation and the feasibility test of linear matrix inequalities (LMIs) under the Parallel Distributed Compensation framework. The main contribution of this paper is that it extends the previously established qLPV model of the aeroelastic wing section with nonlinear friction. It is proven that the extended model can be exactly described after TP type polytopic decomposition. The qLPV model of the aeroelastic wing section with Coulomb friction was transformed to TP type polytopic model form for which LMI based controller was designed. The designed controller is compared to controllers of other authors dealing with the same problem.

This paper presents a novel method for control cooperating robots without any explicit communication line. Fuzzy signatures are used as complex state description method for intention guessing and action selection. Finally a possible cooperative robot application on a realistic example with missing data components will be shown.

There are several technical or technological field, which borrowed inspirations or hints from nature. This way it could be interesting to study, how a multicellular organism develops, by consecutive cell divisions, differentiations and proliferation, from a single cell. This development could be regarded as a decompression process of a highly compressed database. Following and mimicking this procedure we might be able to create a similar database or image processing transformation and compression method. The aim of our research is, finding the method how certain information is stored in the genome, which relates to the physical location and type of each cell of the body. Finding any such relationship, could help us to develop new image transformation and compression method.

Feedback delays are inherent attributes of distributed control systems that usually cause unfavorable effect on the stability of the controlled process. Modelling of such systems is essential for traceable controller synthesis. In this paper we apply the TP Model Transformation to derive a polytopic representation of an LPV model where the time-delay is considered as parameter. The method is introduced via a single degree of freedom impedance model with feedback delay. The resulted model is validated by simulation.

The objective of the discrete-time modeling tools is twofold. First, they give an insight into the basic ideas of discrete-time modeling of dc-dc converters for university students and interested power electronics specialists. Second, as it is being presented below, the interactive calculation tools facilitate the fast and simple model development in WEB browser after entering the basic circuit and load parameters. This feature can especially be useful for the practicing design engineers, since without long calculations with matrix functions the linearized discrete-time system model is immediately and automatically developed in both mathematical form (state-space equations and transfer functions in the Z domain) and also in graphical form (pole-zero map and bode plot).

This paper presents some examples for fuzzy communication and intention guessing from the real life to the cooperation of intelligent mobile robots. In a special experimental environment a new communication approach is investigated for intelligent cooperation of autonomous mobile robots. Effective, fast and compact communication is one of the most important cornerstones of a high-end cooperating system. In this paper we propose a fuzzy communication system where the codebooks are built up by fuzzy signatures. We use cooperating autonomous mobile robots to solve some logistic problems.

In this paper a method is proposed for constructing hierarchical fuzzy rule bases in order to model black box systems defined by input-output pairs, i.e. to solve supervised machine learning problems. The resultant hierarchical rule base is the knowledge base, which is constructed by using structure constructing evolutionary techniques, namely, Genetic and Bacterial Programming Algorithms. Applying hierarchical fuzzy rule bases is a way of reducing the complexity of the knowledge base, whereas evolutionary methods ensure a relatively efficient learning process. This is the reason of the investigation of this combination.

In this paper interpolative and non-interpolative fuzzy rule based machine learning systems are investigated by using simulation results. The investigation focuses mainly on two objectives: to compare the efficiency of the inference techniques combined with different numerical optimization methods for solving machine learning problems and to discover the difference between the properties of systems applying interpolative and non-interpolative inference techniques.

Robots cooperation means also to define the commune task. In order to understand their cooperation the robots must have complete knowledge about all possible states of the work or to understand the context by extract useful information from observation. Present paper focus on the second possibility. We propose a strategy of information extraction and context understanding based on an original data structure, the fuzzy signature and on a priori knowledge, the robot codebook. The paper starts by presenting the concept of the fuzzy signature and exemplify the idea of cooperation by context understanding.
