Opis:: This paper presents a gain scheduled controller design for MIMO and SISO systems in the frequency domain using the genetic algorithms approach. The proposed method is derived from the M-delta structure of closed loop MIMO (SISO) systems and the small gain theory is exploited to obtain the stability condition. An example of real system illustrates the effectiveness of the proposed output feedback gain scheduled controller design method and also the possibility to improve its performance using the genetic algorithm.

Tematy:: hybrid control
equivalent subsystem method
PI controller
Opis:: In this paper two robust control methods for hybrid system are presented. Both methods are usefull for SISO and MIMO systems. Controller design procedure is developed in frequency domain. Equivalent subsystem method is used for controller design in this paper. Stability condition of proposed methods bases on small gain theory and uses additive and inverse additive model type. Two tank water system is presented in the paper and serves as a numerical example to compare effectiveness of described methods.

Opis:: Some of the experimental problems faced when attempting dislocation tomography are discussed. A method of 3D reconstruction of straight line segments with much lower experimental requirements than tomography is proposed. This method is applied to dislocation structures found in two iron aluminium alloys (28 and 40 at.% Al). Resulting information on statistical distribution of dislocation segment lengths and orientations is presented.

Opis:: Fe-Al single crystals of three different compositions (20, 28 and 40 at.% Al) in single slip orientation were studied. Evolution of their surfaces during deformation at room temperature was observed in situ in atomic force microscope. Atomic force microscopy allows us to investigate slip lines on much finer scale than traditional optical observations. Wavy slip bands in $Fe-Al_{20},$ cross-slip in $Fe-Al_{28}$ and weak slip line texture in $Fe-Al_{40}$ are described. Post mortem observations of surfaces of $Fe-Al_{28}$ deformed at elevated temperatures (in the range of yield stress anomaly) are presented as well.

Opis:: Composite multilayer sheets from Al/AlMg3 with 32 alternating layers of Al and AlMg3 were prepared by accumulative roll-bonding and their thermal stability was studied. Recrystallized 2 mm thick sheets of a commercial twin-roll cast AlMg3 alloy and high purity Al99.99 served as input materials. Electrical resistivity measurements were used for the integral monitoring of solute atoms distribution during annealing. Light optical microscopy was employed for the direct grain-size determination and recrystallization description. Post-mortem electron microscopy observations were performed on as-prepared and annealed specimens and they were combined with in situ heating electron microscopy in order to explain the observed annealing effects. A broadening of Al layers during annealing was observed and related to diffusion of magnesium.
