Abstract An active disturbance rejection controll Strategy with lead compensation and feedforward (ADRC-LCF) is proposed to address the problem of poor power quality at output direct-to-direct converter when microgrid subject uncertain disturbances. The control strategy achieves reconstruction self-anti-disturbance controller by connecting over-compensator in series introducing differential fee...

This work focuses on design of trajectory-tracking control based active disturbance rejection (ADRC) controller for knee joint exoskeleton device. The device is worn by disable patients and it actuated ADRC to perform the exercises prescribed physician doctor rehabilitation humanoid's lower limb. In order improve tracking performance robustness characteristics ADRC, minor modification has been ...

Considering the unavoidable and unmeasured disturbances, parameter variations and position measure error of real motion control applications, a novel controller is developed for the motion control of permanent-magnet synchronous motors (PMSM). First, an active disturbance rejection controller (ADRC) based on extended state observer (ESO) is employed to ensure the high performance of the entire ...

An Active Disturbance Rejection Control (ADRC) scheme is proposed for a trajectory tracking problem defined on a nonfeedback linearizable Furuta Pendulum example. A desired rest to rest angular position reference trajectory is to be tracked by the horizontal arm while the unactuated vertical pendulum arm stays around its unstable vertical position without falling down during the entire maneuver...

Three-motor synchronous coordination system is a MI-MO nonlinear and complex control system. And it often works in poor working condition. Advanced control strategies are required to improve the control performance of the system and to achieve the decoupling between main motor speed and tension. Cerebellar Model Articulation Controller coupled with Active Disturbance Rejection Control (CMAC-ADR...

UAV flying in the air is affected by external airflow factors, and system has characteristics of underdrive, nonlinear uncertainty, which makes flight state become complicated. The trajectory tracking studied using Active disturbance rejection control (ADRC) algorithm. ADRC algorithms include differentiator, extended observer error feedback law. active decoupling track studied, introduces stati...

To solve the oxygen supply problem of proton exchange membrane fuel cell (PEMFC), this paper presents a reduced-order active disturbance rejection control method for PEMFC air intake system based on estimation excess ratio(EOER-RADRC). First, control-oriented third-order nonlinear model was established system. Then, model, extended state observer designed to unmeasured cathode pressure paramete...

In this article, we consider the state feedback stabilization of ODESchrödinger cascaded systems with the external disturbance. We use the backstepping transformation to handle the unstable part of the ODE, then design a feedback control which is used to cope with the disturbance and stabilize the Schrödinger part. By active disturbance rejection control (ADRC) approach, the disturbance is esti...

In this paper, an algorithm is developed to reject time and spatially varying boundary disturbances from a multi-dimensional Kirchoff plate via boundary control. The disturbance and control input are assumed to be matched. The active disturbance rejection control (ADRC) approach is adopted for developing the algorithm. A state feedback scheme is designed to estimate the disturbance based on an ...
