https://doi.org/10.4467/2353737XCT.16.064.5413The paper presents a new approach to the design of the solar thermal system controller which is characterized by modular arrangement. The proposed solution enables the integration of controller functions that significantly improve user comfort and the overall reliability of the system. These functions may include both security operations (control of blinds for solar collector, emergency power supply) as well as system monitoring (heat meter, data logger with memory card, Internet-based monitoring, weather station).

The paper presents results of the identification of the multivariable model of the fluidized bed
boiler derived in the form of transfer function matrix. Conditions of the experiment that ensure
the identifiability of model dynamics while limiting the risk of emergency boiler shutdown was
proposed. Typical disturbances of the combustion process including division into measurable
and immeasurable ones as well as the method to identify the impact of these disturbances on
the outputs of the model was formulated. Possible application of the model in the model-based
controllers such as predictive or adaptive IMC (Internal Model Control) was indicated.

https://doi.org/10.4467/2353737XCT.15.186.4391This paper presents selected aspects of an alternative power supply for small HVAC systems. The application of a system based on photovoltaic cells together with energy accumulation in VRLA gel batteries was analysed. The results were obtained using laboratory installation and were compared with the predicted data.
