US 2013/0018487 A1 · SCALING AND PARAMETERIZING A CONTROLLER

Abstract

Controller scaling and parameterization are described. Techniques that can be improved by employing the scaling and parameterization include, but are not limited to, controller design, tuning and optimization. The scaling and parameterization methods described here apply to transfer function based controllers, including PID controllers. The parameterization methods also applies to state feedback and state observer based controllers, as well as linear active disturbance rejection controllers. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the application. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Dependent claims

A graphical interface for interacting with a controller of an Nth order closed-loop system, comprising:

a first input field configured to receive first input that adjusts a control system bandwidth ωc of a parameterized controller, wherein the control system bandwidth ωc is a sole control tuning parameter of two or more gains of the parameterized controller and defines a common location of N poles of a Nth order closed-loop system including the controller and a plant, wherein the two or more gains are represented by respective two or more functions in which an only variable of the respective two or more functions is the sole control tuning parameter, and wherein N is an integer;
and
a first display field configured to display at least one performance parameter of the Nth order closed-loop system.

Dependencies are inferred from the claim text.
