Abstract:
1. A system for controlling a machine, comprising: a. an input signal, wherein the input signal conveys a desired operating parameter of the machine; b. a first parameter signal, wherein the first parameter signal conveys a measured parameter of the machine taken at a first time; c. a first controller, wherein during a first cycle, the first controller receives the input signal and the first parameter signal and generates a control signal to the machine based on the input signal and the first parameter signal; d. a second controller, wherein during the first cycle, the second controller receives the first parameter signal and the control signal and generates a predicted parameter signal based on the first parameter signal and the control signal; e. a second parameter signal, wherein the second parameter signal conveys the measured parameter of the machine taken at a second time; f. a feedback circuit, wherein the feedback circuit receives the second parameter signal and the predicted parameter signal and generates a feedback signal based on the second parameter signal and the predicted parameter signal; and g. a comparator, wherein during the first cycle, the comparator receives the feedback signal and transmits the feedback signal to the second controller if a predetermined threshold is not met.
