Carl H. Sturmer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Easily tuned and robust control algorithm for single or multiple variable systems
    Patent number: 7546170
    Abstract: A controller and associated methods. A controller has an input for a controlled variable; a proportional term; an integral term; and a predictive term. The predictive term has an error-predictive subterm including at least a past value of an error; and a command-predictive subterm including at least one past value of a control command value; and an output. The controller can apply the predictive term and at least one of the proportional term and integral term to generate a command for the output. A method for controlling a process variable is also provided including applying a predictive term having an error-predictive subterm that includes at least a past value of an error and a command-predictive subterm that has at least a past value of a control command. The method further includes the step of generating a command based on the results of the applying the terms.
