The transparent building element filled with Phase change materials (PCMs) represent an innovative solution that can achieve thermal comfort in buildings lowering the cooling and heating demand. There are many different PCMs which are used in the building element. Salt hydrates can absorb a large amount of energy and have properties similar to water. Nevertheless, these materials have a tendency to supercool (supercooling effect) and to incongruent melt. This paper reports the results of the measurement specific four-pane window filled with a PMCs. Thermal properties of the window were tested in the climate simulator where the climatic conditions were dynamically controlled. The measurement confirmed high thermal inertia of the window and also reducing heat transfer through the window. © The Authors, published by EDP Sciences, 2017.

This paper proposes a robust coalitional distributed model predictive control algorithm suitable for input coupled sub-systems. The core idea is based on a distributed iterative implementation with minimum information exchange, in which the coupling information is regarded as bounded additive uncertainty. If the disturbance received from the neighbours is too large for the local optimization problem, then a coalitional strategy is adopted. The closed-loop stability is guaranteed via terminal constraint. The performance of the coalitional strategy is compared with an iterative min-max distributed model predictive controller and a centralized model predictive controller.

The outstanding feature of the pneumatic artificial muscle is its high power to weight ratio vastly outperforming both pneumatic cylinder and DC motor. This feature is very important for using of pneumatic muscle-based actuators in industrial robotic systems where high forces and stiffness of mechanism are often required. The most common so far produced and used type of pneumatic artificial muscle is McKibben muscle and it is now made commercially available by different companies (e.g. Festo). In the paper there are described some of its characteristics and principles of control important for using as actuator for industrial robotic applications.

The paper presents the interim results of our research on the developing methodological procedure which could be used for assessment of a thermal stability of buildings with regards to its thermal accumulative parameters. The principle of testing is based on a combination of computer simulation of cooled room model developed in COMSOL Multiphysics software and on theoretical calculations with respect to compliance with valid European and Czech technical standards used in building industry and architecture under conditions obtained by real measurement for the room to be tested. The presented example shows the effect of the heataccumulation properties of the outside wall insulation materials on the course of the cooling room for winter conditions. © The Authors, published by EDP Sciences, 2017.

In this paper, a non-cooperative distributed model predictive control (DMPC) algorithm for tracking constant references is developed and evaluated. As such, an augmented model is employed (i.e. the control loop is embedded with integrators) and the augmented state contains the state increments and the error between the reference and the predicted output. The algorithm is tested in real life experiments on the quadruple tank process with non-minimum phase behaviour. The experimental results show acceptable performance index for the DMPC method when compared with the centralized approach. © 2016

The paper is focused on systems with delay terms at the left (and the right) side of differential equations. Analysis and synthesis of delay systems can be conveniently studied through a special ring of RQ-meromorphic functions. The control methodology is based on a solution of Diophantine equations in this ring. Final controllers result in the Smith predictor like structure. controller parameters are tuned through a pole-placement problem as a desired multiple root of the characteristic closed loop equation. The methodology is illustrated by a stable second order transfer function with a dead-time term. Then the paper brings an autotuning method as a combination of biased-relay feedback estimation and the proposed algebraic control design. The developed approach is illustrated by examples in the Matlab and Simulink environment.

Examination of the control of a high-speed vehicle is essential to achieve autonomous navigation on high speed roads. Velocity profile generation is one of the challenging problems. In this paper we analyze the efficiency of an on-line velocity profiler algorithm. The presented method is based on a receding horizon implementation in which the vehicle executes part of the computed optimal trajectory, while simultaneously optimizing the path up to a new horizon. The search space at each optimization step is considerably reduced, which results in reduced computational cost. We present an analysis of the horizon length selection and the impact on the running times compared to the infinite-horizon solution.

In this paper, the uncertain dynamic active pantograph-catenary system which considers the effect of time-varying stiffness resulting from the uneven overhead wire is investigated to improve current collection for light rail vehicle. In order to achieve stable current collection, and hence improve the performance of the overall electricity supply, sliding mode control strategy and adaptive fuzzy sliding mode control scheme are combined. The uplift force which is applied to pantograph frame by actuator is constructed by incorporating fuzzy neural network (FNN) and sliding mode control to attenuate the chattering problem resulting from the sliding mode control. Based on the Lyapunov stability theorem, the active control law and adaptive laws for the free parameters of the FNNs can be derived to effectively suppress vibration of the pantograph system.
