Time-Optimal Control Strategies For Residential Heating Systems Using State-Space Techniques , Roy R. Crawford Jan 1983

Time-Optimal Control Strategies For Residential Heating Systems Using State-Space Techniques , Roy R. Crawford

Retrospective Theses and Dissertations

Past research on the optimization of building performance has resulted in various control strategies which minimize building energy consumption while maintaining a specified level of indoor environmental quality (e.g., thermal comfort, mass air quality, lighting levels). The optimal control strategy proposed in this study uses a "performance index," which quantifies the "costs" of energy consumption and indoor environmental quality, to mathematically express the operating performance of a building;A procedure is developed for deriving a dynamic system model which relates the indoor environmental quality to the energy consumption of a building. A system model is derived, semi-empirically, from actual ...

Electrical Breakdown And Ignition Of An Electrostatic Particulate Suspension , Tae-U Yu Jan 1983

Electrical Breakdown And Ignition Of An Electrostatic Particulate Suspension , Tae-U Yu

Retrospective Theses and Dissertations

An electrostatic suspension concept was successfully utilized in generating a uniform particulate cloud between two parallel electrodes in air at atmospheric pressure in order to investigate the effect of this cloud on electrical breakdown, electrical discharge, and ignition of combustible gases. Electrical breakdown was initiated by a fast moving injected needle electrode which resulted in a minimal disturbance of the suspension;It was observed that when using a negative needle (electrode), neither the breakdown voltage nor the needle position at breakdown depended significantly on the needle velocity or the particle number density. Conversely, the positive needle (electrode) breakdown voltage and ...
