Patent attributes
A distributive adaptive control system for HVAC control and a method for controlling the temperature in a building with one or more zones is disclosed. The control system and method are based on a design that may accommodate buildings with multiple interconnected thermal zones. The system includes a controller for each zone of the building. Each controller is designed to regulate temperature while attenuating the effect of directly neighboring zones, wall temperature, weather conditions and heat gains. The control mechanism does not require any prior accurate knowledge of system parameters but instead calibrates itself to meet the needs of each thermal zone. An appropriate adaptive law may be used for learning the building and HVAC system parameters and auto-calibrating the controller. The proposed system and method can extend the life of the HVAC by compensating for a wide range of tear and wear and other defects in the equipment.
