This paper deals with design of multichannel measurement system for strain gauge sensor evaluation in laboratory of mechanical engineering. Device is based on 8-bit Freescale microcontroller MC9S08GB60 which is due its properties intended for general purpose applications. Device implements modular hardware design enabling easy functionality expansion in future demands. This is fulfilled by dividing of the whole measurement system to main board and input / output eventually measurement modules. Main board of the device contains master microcontroller, USB communication interface, power supplies and interface for expansion cards. Modules for strain gauge sensor evaluation consist of amplifier with selectable gain followed by 4th order Bessel low-pass filter eliminating ripple in analog signal and finally 12-bit analog-to-digital converter connected via serial peripheral interface (SPI) and other control signals with main board. Communication with supervision system is provided by USB interface which is recognized as standard serial port in host operating system.

The main aim of this contribution is to introduce the fundamentals of the Fractional Order Calculus (FOC) and outline its possible application to analysis and synthesis of control systems. The basic theoretical concepts of FOC are followed by techniques for potential fractional order systems description and stability investigation. Moreover, the paper offers the overview of the existing fractional order controllers and highlights the benefits of the fractional approach in comparison with the classical integer one.

This contribution is focused on comparison of two basic approaches to uncertainty modelling and corresponding robust stability analyses for a system with uncertain time-delay. A paper bleaching process, described both as a system with parametric uncertainty and in the form of unstructured multiplicative uncertainty model, is considered as a testing plant. The robust stability of closed control loop with selected controller and appropriate uncertain model of controlled plant is verified and obtained results are compared.

The main idea of this project is to simulate the thermal construction responses in dependence on changing boundary conditions. In order to predict environmental temperature precisely a model of one room has been developed and implemented in COMSOL Multiphysics. A finite element model was developed in 3D coordinates in order to achieve illustration of an air and an energy movement and to simulate the transient process in the walls. Notwithstanding, this model was not accurate enough for application in building conditions. Main goal of this paper is in updating current model to get results with sufficient accuracy. Temperature course of the model is analyzed and compared to the experimentally measured temperature data.
