The paper investigates the problem of stability analysis of differential linear repetitive processes with norm-bounded uncertainties. By applying a version of the Kalman-Yakubovich-Popov (KYP) Lemma, relaxed conditions for stability along the pass are proposed in terms of linear matrix inequalities (LMIs), which can be easily solved via standard numerical software. In particular, the conservatism of the resulting condition for stability along the pass can be significantly reduced by dividing the entire frequency domain into several sub-intervals and by applying KYP Lemma to each frequency sub-interval. Moreover, the obtained stability result is suitable for extension to robust control law design for processes with norm bounded uncertainty. Finally, a numerical example is provided to illustrate the application of the developed results.

The state of grinding wheels of automated grinding lines can be evaluated by monitoring their vibration and temperature, so that a condition-based approach can be used for their maintenance. However, there are some limitations of condition monitoring, which may conduct to some uncertainty or vagueness in accomplishing diagnostics. Within this framework, the aim of this study is the employment of a fuzzy logic for planning the maintenance policy of the grinding wheels of automated grinding lines.

The paper considers the modeling of active heating or natural cooling of a cylindrical body, - either vertically or horizontally arranged. The position dependency of the coefficient of convective heat transfer along the surface of the body on this process is investigated in detail. It turned out that its nonuniformity must be taken into account when solving problems of controlled heating for bodies with low thermal conductivity. An identification of the model parameters leads to results that are in good agreement with values from the literature for the experimental setup — a cylindrical body heated from both ends by two Peltier elements.

Image processing technologies nowadays are widely used in quality control. A new automated quality control system saves resources. Quality control in the fertilizer industry is carried out without interruption. Only indirect measurements can achieve the required quality production efficiency. This article presents the methodology for calibrating indirect particle measurement methods. Particle analysis is performed by processing digital images. Correction of results is carried out with a sieve correction factor. In this work, studies have been carried out using linear regression polynomial function and artificial neural network. With the latter, the best results are achieved with sufficient data for training.

In this paper we presented a method for human being identification based on ECG supported by Artificial Neural Networks. We also propose structure of such identification system with description of its functional elements. To provide an insight into efficiency of the proposed methodology we compare it to alternative approaches based on Logistic Regression and K-Nearest Neighbour. All experiments were performed on several representative data (existing ECG records of real patients).

At present, in human–machine interaction systems, communication may be realized with the visual representation of a person. The use of human visualization requires human mechanisms of movement and social behaviour analysis. Naturally, the human body is in subtle motion. These small changes in body position are unintentional and in most cases involuntary. In the simulation of a virtual person, this type of motion can provide pseudo human behaviour. Therefore the paper addresses the problem of simulating human head idle gestures for avatars. The idle mode is introduced in order to increase the realism of the avatar's behaviour. The proposed mode involves the situation when the avatar is waiting for external events and can eliminate the frozen state of the character.

The classical Cayley-Hamilton theorem is extended to fractional continuous-time linear systems. For single fractional order system the Cayley-Hamilton theorem is extended to basic continuous-time functions determining the solution of the system. The Cayley-Hamilton theorem is also extended to different orders fractional linear systems.

This paper presents a new methodology to guide and control flexible wings UAV based on a stereo vision system with advanced fuzzy logic algorithms. This system allows to detect wing's deflections and shapes by using the novel Deflection-Detection Vision System (DDVS). This methodology has three different steps. First, the shape of the wing was identified by the determinant the deflection points on the wing using the stereo camera. Second, the fuzzy logic algorithm was used to classify the shapes of the wing and to determine the flight parameters such as, speed, angle of attack and roll angle. Finally, an autopilot controller based on intelligent, Adaptive Neuro-Fuzzy Inference System (ANFIS) algorithm was designed. Extensive, experimental studies were performed in wind tunnel to determine the characteristics of the flexible wing. The testing were performed for wind speeds ranging from 11 to 31 km/h, angles of attack ranging from −20 deg to +20 deg. The experimental results were extended and verified with simulation experiments for wider ranges of velocities and angle of attack.

The paper introduces a new path planning method for ships. It is applied to calculate a safe trajectory for a ship in a collision situation at sea. The algorithm takes into account both static (lands, shallows) and dynamic obstacles (encountered ships) and returns a solution in near-real time. The algorithm is inspired by the Artificial Potential Field method and uses a general concept of this approach. The paper presents the description of a new method and results of simulation studies concerning simple and more complex navigational situations. Results demonstrate the effectiveness of proposed method for ships path planning.

This paper deals with a manufacturing system which provides on the output a fixed mixture of various products in a repetitive series. The system works accordingly to so called job-shop strategy, namely each product has its own independent technological route, various for different products. Based on our own achievements obtained for classical job shop batch scheduling problem, we propose the cyclic manufacturing strategies for so called non-interlaced and interlaced modes. Proposed approach differs significantly from those known so far in the literature and is much more advantageous, due to lesser computational complexity and faster convergence to the optimal solution. We proposes some new properties useful for finding the minimal cycle time for fixed (given) job processing order on the base of graph paths as well as special features of the problem.
