SCALING AND PARAMETERIZING A CONTROLLER

摘要

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.

1. A system, comprising:
a plant; and a controller embodied on at least one of an integrated circuit, a microprocessor, or a programmable logic device, wherein the controller is configured to control the plant, and wherein the controller comprises two or more gains that are functions of a single control tuning parameter comprising a control system bandwidth of the controller, the two or more gains are represented by respective two or more mathematically related functions whose only variable is the single control tuning parameter, and the control system bandwidth defines a common location of N poles of an Nth order closed-loop system comprising the controller and the plant, where N is an integer.
