Abstract
A system for controlling temperature of a building space includes HVAC equipment configured to serve the building space, a plurality of sensors configured to measure a plurality of parameters relating to the building space, and a control system. The control system is configured to receive data from the plurality of sensors, generate a plurality of disturbance heat flow estimates for the building space based on the data from the plurality of sensors, determine a feedforward heat flow contribution based on the disturbance heat flow estimates, determine a feedback heat flow contribution based on a measured temperature of the building space and a temperature setpoint for the building space, combine the feedforward heat flow contribution and the feedback heat flow contribution to determine a rate of heat flow to be provided to the building space by the HVAC equipment, and control the HVAC equipment to provide the rate of heat flow.
