SYSTEMS AND METHODS FOR AUTOMATICALLY CREATING AND USING ADAPTIVE PCA MODELS TO CONTROL BUILDING EQUIPMENT

摘要

A building management system includes connected equipment and a predictive diagnostics system. The connected equipment is configured to measure a plurality of monitored variables. The predictive diagnostics system includes a communications interface, a principal component analysis (PCA) modeler, a controller. The communications interface is configured to receive samples of the monitored variables from the connected equipment. The PCA modeler is configured to automatically assign each of the samples of the monitored variables to one of a plurality of operating states of the connected equipment and to construct a PCA model for each operating state using the samples assigned to the operating state. The controller is configured to use the PCA models to adjust an operation of the connected equipment.
