New LADRC scheme for fractional-order systems
Alexandria Engineering Journal, 2022 Active Disturbance Rejection Control (ADRC) is a very promising recent concept for the design of controllers to control systems with uncertainties. Based on an extended state observer, this control structure allows both external disturbances and modeling uncertainties to be actively rejected.
