Extended active disturbance rejection controller

Short Description

Controllers, systems, and methods for feedback control of various systems.


An ADRC controller that comprises one or more computer components, that extend, build upon and enhance the use of ADRC controllers and provide enhanced performance and utility. Specifically, the ADRC controller utilizes a predictive computer component that predicts future values of the plant output as well as future estimates of the system state and generalized disturbance.
