IDENTIFYING SUITABLE MODELS FOR ADAPTIVE MODEL PREDICTIVE CONTROL OF BUILDING HVAC USING MOVING HORIZON ESTIMATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240019156 titled 'IDENTIFYING SUITABLE MODELS FOR ADAPTIVE MODEL PREDICTIVE CONTROL OF BUILDING HVAC USING MOVING HORIZON ESTIMATION
Simplified Explanation
The patent application describes a model that combines a differentiable physics model of a building with a data-driven model of a heating, ventilation, and air-conditioning (HVAC) system. The model learns the behaviors of the HVAC system components based on past performance data and inputs. The model updates the parameters of both the physics model and the data-driven model using moving horizon estimation. It also determines the current input to the controlled components using model predictive control.

Original Abstract Submitted
a differentiable physics model of a building is used that defines thermodynamic relationships between zones of the building and a heating, ventilation, and air-conditioning (hvac) system. a physics-constrained, data driven model learns behaviors of controlled components of the hvac system. for each of a series of times during online operation of the hvac system, past state values are recorded representing a performance of the hvac system in the building and past inputs to the hvac system to maintain the states. the past state values and the past inputs are input into the differentiable physics model and the data driven model to: jointly update first parameters of the differentiable physics model and second parameters of the data driven model, e.g., using moving horizon estimation; and determine a current input to the controlled components, e.g., using model predictive control.
