METHODS AND SYSTEMS FOR COORDINATING THE CONTROL OF HVAC UNITS
First Claim
1. A method of controlling an environmental maintenance module using a plurality of sensors, the method comprising:
- receiving a first set of environmental measurements, each environmental measurement being from a respective one of the sensors;
determining differences between the environmental measurements and a plurality reference values, each difference being between a respective environmental measurement and a corresponding reference value; and
calculating a change value for an operational parameter of the environmental maintenance module, wherein the change value includes contributions derived from at least two of the differences.

Abstract
A control strategy for heating, ventilating, and air-conditioning (HVAC) units used to condition the environment in data centers and other commercial buildings such as retail stores with an open-plan design is provided to coordinate the operation of the actuators of the HVAC units. A supervisory controller receives feedback signals from a plurality of environmental sensors and uses a set of references values to determine control signals to the actuators of the HVAC units. A pseudoinverse of a transfer function matrix G may be used to determine the control signals from errors in the feedback signals relative to the reference signals.
