Abst rac t . The problem of systematically synthesizing hybrid controllers that satisfy multiple requirements is considered. We present a technique, based on the principles of optimal control, for determining the class of least restrictive controllers that satisfy the most important requirement (which we refer to as safety). The system performance with respect to the lower priority requirement ...

In this paper, a new solar-heated generation system with capacity of 10kW is designed. The system is based on solar-heated Rankine cycle. The CPC solar energy collector array is used as the main heat source, and the gas boiler as the assistant heat source. The heat storage facility provides heat for put-off 24 hours generating without sun’s radiation. The paper is focused on the analysis of fou...

This paper investigates the optimisation of pressurised steam production for a power plant, via a number of interconnected boilers of varying efficiency characteristics. The aim of the scheme is to provide the required amount of steam whilst allowing sufficient spare capacity to compensate for boiler failure. The proposed solution uses evolutionary techniques based on genetic and memetic algori...

as part of the OptiEnR research project, the present paper deals with optimizing the multi-energy district boiler of La Rochelle (France) adding to the plant a controlled thermal storage tank. This plant supplies domestic hot water and heats residential and public buildings, using renewable and fossil resources. Due to the complexity of the district boiler as a whole and the strong interactions...
