Patent ID: 8571691

Claim:
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 ω c of a parameterized controller embodied on a processor, wherein the control system bandwidth ω c 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 comprising the parameterized controller and a plant controlled by the parameterized controller, where N is an integer, and wherein adjustment of the control system bandwidth ω c in accordance with the first input causes adjustment of the N poles of the Nth order closed-loop system, and the two or more gains are represented by respective two or more functions wherein an only variable of the respective two or more functions is the sole control tuning parameter; a first display field configured to display at least one performance parameter of the Nth order closed-loop system; and one or more second input fields configured to receive second input specifying one or more design objectives for control of the plant, wherein the graphical interface is configured to set an initial value for the control system bandwidth ω c based at least in part on the one or more design objectives.
