1. A method for controlling a multivariable system including the steps of:

  • a) receiving a plurality of sensor signals indicating current conditions of the system which are periodically sampled;

    b) receiving a plurality of commands;

    c) determining a desired change in output of the system for at least one future controller sample based upon the commands and sensor signals;

    d) formulating the problem of determining actuator commands to achieve the change in output by the at least one future controller sample as a quadratic programming problem that includes physical limits or constraints of the system.
