1. A method of operating an industrial process by an integrated quadratic controller (IQC) comprising a processor and a memory, the IQC communicatively coupled through a communication network to multiple load controllers, each one of the multiple load controllers is associated with a respective load, each of the respective loads associated with operation of a portion of the industrial process, the memory containing instructions for performing the method comprising:
determining, by the IQC, a desired target output process value (PV) for a total output PV for the industrial process defined as an input in a single-input multiple-outputs (SIMO) process;
determining, by the IQC, a plurality of manipulated-variables (MV)s, for the multiple-outputs, for each MV of the plurality of MVs associated with operation of each of a respective load controller of the multiple load controllers within the industrial process, wherein the respective MV of the plurality of MVs are associated with each one of the multiple loads and control a rate of operation for a respective load impacting the total output PV of the industrial process, wherein each one of the multiple loads has an associated load controller operating based upon the respective MV;
determining, by the IQC, quadratic programming (QP) for optimizing proportional action gains for associated quadratic coefficients for the determined plurality of MVs, given the target output PV, to maximize profitability of the total output PV of the industrial process;
integrating, by the IQC, the QP optimized proportional action gains for the determined plurality of MVs of the multiple load controllers, wherein each of the multiple load controllers using proportional action feedback to control the respective output; and
applying, by the IQC, an updated output state map defining modified MVs of the plurality of MVs from the integrated QP optimized proportional action gains by communicating the modified MVs from the output state map via the communication network to each of the multiple load controllers to control the rate of operation and respective loads associated with each of the load controllers in the industrial process to obtain the total output PV from the multiple load controllers within a margin of the target output PV.
