Building hvac sytem with fault-adaptive model predictive control

A controller for automatically adapting a predictive model used to control a heating, ventilation, or air conditioning (HVAC) system in a building to make adjustments based on a detected fault in the HVAC system, the controller comprising a processing circuit configured to:

• obtain an indication of the detected fault in the HVAC system;
• determine an impact of the detected fault on an operational performance of at least one of the HVAC system or a zone of the building;
• adjust one or more parameters of the predictive model based on the impact of the detected fault to generate a fault-adapted predictive model;
• and
• operate the HVAC system to control an environmental condition of the building using the fault-adapted predictive model.

One or more non-transitory computer-readable storage media having computer-executable instructions stored thereon that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• obtaining an indication of a detected fault in a system;
• determining an impact of the detected fault on an operational performance of the system;
• adjusting one or more inputs of an optimization problem based on the impact of the detected fault to generate a fault-adapted predictive model;
• and
• operating the system to control a variable state or condition of the system using the fault-adapted predictive model.
