Modeling and control for an integrated thermal hydronic system

摘要: This paper presents modeling and control methods for an integrated thermal hydronic system (ITHS) consisting of a solar collector, storage unit booster. Control inputs are: valves activation time, pitch angle, pump rate compressor rate, measurements temperatures at critical points, disturbances ambient air temperature, source water temperature the position sun relative to plane collector. In this context, problem maintaining within given range is considered. To address problem, model developed based on lumped-parameter analysis. Using model, three controllers are tested in simulations, i.e., on-off controller, PI controller scheduling controller. The will be useful developing optimal high efficiency ITHS.
