AIR CONDITIONING CONTROL IN WT MODE WITH TIME, FUEL, AND ENERGY DEMAND OPTIMIZATION

摘要

The paper discusses automatic temperature control in a closed space by means of air condition-ing In WT mode (variable flow, variable temperature). The optimal controller controls two external analog regulators. Pontryagin's maximum principle is used to optimize the control on the basis of a multicriterion target function. A study is made on the nonstationary heat transport through part of the wall bounding the space. The most substantial perturbations accompanying air conditioning have not been incorporated in the third-order model. The resulting optimal control law is complicated and unsuitable for computer processing.
