Building control system with smart edge devices having embedded model predictive control

An environmental control system for building equipment that operates to affect a variable state or condition within a building, the system comprising:

• one or more environmental sensors configured to measure one or more environmental conditions affecting the building;
• the building equipment that operates to affect the variable state or condition within the building;
• and
• a controller comprising a processing circuit configured to:
• obtain sensor data indicating the one or more environmental conditions of the building from the one or more environmental sensors;
• determine an amount of available processing resources at the controller or at the building equipment;
• automatically scale a level of complexity of an optimization of a cost function based on the amount of available processing resources;
• perform the optimization of the cost function at the automatically scaled level of complexity to generate a first setpoint trajectory for the building equipment, the first setpoint trajectory comprising operating setpoints for the building equipment at a plurality of time steps within an optimization period;
• and
• operate the building equipment based on the first setpoint trajectory to affect the variable state or condition within the building.

A method for operating building equipment to affect a variable state or condition within a building, the method comprising:

• obtaining sensor data indicating one or more environmental conditions of the building;
• determining a capacity to perform an optimization of a cost function at a smart edge controller or at the building equipment;
• automatically scaling a level of complexity of the optimization of the cost function based on the capacity;
• performing the optimization of the cost function at the automatically scaled level of complexity to generate a first setpoint trajectory for the building equipment, the first setpoint trajectory comprising operating setpoints for the building equipment at a plurality of time steps within an optimization period;
• and
• operating the building equipment based on the first setpoint trajectory to affect the variable state or condition within the building.
