System and method for power optimizing control of multi-zone heat pumps

A method for vapor compression system, comprising:

• receiving from a set of primary sensors, a primary set of system outputs by a primary controller, wherein the primary controller produces a primary set of control inputs for a set of primary actuators, to regulate one or more zone temperatures to primary controller set-points and to regulate one or more critical process variables to the primary controller set-points;
• receiving from a set of secondary sensors, a secondary set of system outputs, by a secondary controller, wherein the secondary controller produces a secondary set of control inputs for a set of secondary actuators, to minimize an overall system power consumption, wherein the secondary controller uses an executable program stored in a memory, to compute a gradient of a power consumption function, a steady-state gain from the secondary control inputs to the secondary system outputs, and a compensator that includes integral action, and wherein some of the primary controller set-points are outputs of the secondary controller;
• and
• outputting, via an output interface, the secondary set of control inputs to one or a combination of, some of the secondary actuators, or some of the primary controller set-points regulate the one or more zone temperatures.
