Design of active disturbance rejection controller for compass-like biped walking
International Journal of Advanced Robotic Systems, 2018 This article proposes an active disturbance rejection controller design scheme to stabilize the unstable limit cycle of a compass-like biped robot. The idea of transverse coordinate transformation is applied to form the control system based on angular ...

First-Order Linear Active Disturbance Rejection Control for Turbofan Engines
Energies, 2023 Proportional-integral (PI) control is widely used in turbofan-engine control, while first-order linear active disturbance rejection control (FOLADRC) is a possible approach to update it. This paper investigates FOLADRC. In methodology, it proposes a new block diagram of FOLADRC, which shows that FOLADRC can be viewed as a PI controller, a low-pass ...
