Claim Text:
1. A method of dynamically tuning control of a steam generating boiler system, comprising: determining, by an error detector, a presence of an error corresponding to a temperature of output steam, wherein the output steam is generated by the steam generating boiler system for delivery to a turbine, and the determination of the presence of the error is based on a magnitude of a difference between a signal indicative of a measured temperature of the output steam received at the error detector and a signal indicative of a setpoint received at the error detector; providing, by an output of the error detector to a dynamic matrix controller of a control loop of the steam generating boiler system operating to control the temperature of the output steam, a signal corresponding to the error; receiving, at the dynamic matrix controller, (i) the signal corresponding to the error provided by the output of the error detector, (ii) a signal indicative of a rate of change of a disturbance variable generated by a device used in a portion of the steam generating boiler system, the portion of the steam generating boiler system excluding any devices included in the control loop, (iii) the signal indicative of the measured temperature of the output steam, and (iv) the signal indicative of the setpoint; adjusting, by the dynamic matrix controller based on the signal corresponding to the error, the signal indicative of the rate of change of the disturbance variable; generating, by the dynamic matrix controller, a control signal based on the adjusted signal indicative of the rate of change of the disturbance variable of the portion of the steam generating boiler system; and controlling, based on the control signal, a manipulated variable of the control loop of the steam generating boiler system to thereby control the temperature of the output steam.
