Temperature control of a utility system for an Open Plate Reactor

A new reactor type has been designed by Alfa Laval AB,the open plate reactor (OPR). It combines good mixing with high heat transfer capacity. With the new open plate reactor, highly exothermic reactions can be produced using more concentrated reactants. In the paper, the reactor type is presented and a model from first principles is derived. The paper concerns the control properties of the platere

Optical Design and Characterization of Solar Concentrators for Photovoltaics

Stationary solar energy concentrators are a promising option for decreasing the price of photovoltaic electricity. This thesis studies stationary concentrators in PV/Thermal applications. The studied systems are parabolic troughs intended for building integration. The first chapters briefly explain the optics of solar energy concentrators. The theoretical maximum concentration ratios of two and th

Designing Bandwidth-Efficient Stabilizing Control Servers

Guaranteeing stability of control applications in embedded systems, or cyber-physical systems, is perhaps the alpha and omega of implementing such applications. However, as opposed to the classical real-time systems where often the acceptance criterion is meeting the deadline, control applications do not primarily enforce hard deadlines. In the case of control applications, stability is considered
