A structure having convergence of a control system and a data analytics system. The control system may involve input-output models of items, for example, homes, buildings and process plants. The system may use sensor data and scientific principles to implement control models. The models may help to precisely achieve a desired value of a parameter. The data analytics system may involve analysis of diverse data and may create insights of the items. The control system plus the data analytics system may close the loop between insights and on-premise controls of the items represented by the input-output models. The control and data analytics systems may merge the best of both worlds to solve difficult issues pertaining to the items. The structure may be for comfort control, energy reduction, and so on, having improved performance based on the convergence.
