Hybrid control and evolutionary decision support within a sustainable environment

By R. Stirrup and A.J. Chipperfield


Due to the increased global demand for energy, and the potential dangersof relying too heavily on our fossil fuel reserves, more and more research is being directed towards alternative, and preferably reusable or sustainable forms of energy supply. Many of these real world systems have operating regions that exhibit varying degrees of non-linearity. An example of this are the significant variations in the dynamic characteristics of a distributed collector field within a solar power plant. Here a control scheme employs a fuzzy PI controller, with feedforward, for the highly nonlinear part of the operating regime and gain scheduled controller for the more linear part of the operating envelope. In order to satisfy performance characteristics for the plant at different points in the operating regime, a multiobjective genetic algorithm with enhanced decision support system, is used to design the parameters of the fuzzy controller
