Autonomous Navigation of an Unmanned Underwater Vehicle via Safe Reinforcement Learning and Active Disturbance Rejection Control

Journal of Marine Science and Engineering
A two-layer control framework for unmanned underwater vehicle (UUV) navigation is proposed, combining a lower-layer active disturbance rejection controller (ADRC) with an upper-layer safe reinforcement learning (RL) policy for obstacle-avoidance ...

Active Disturbance Rejection Control of a Neutralisation Process

This paper presents active disturbance rejection control (ADRC) of pH in a neutralisation process. As pH dynamics is highly nonlinear and not control-affine, direct application of ADRC using pH as the controlled variable is not effective.
