Adaptive Narrow Band Disturbance Rejection in Active Vibration Control

This paper presents a methodology for feedback adaptive control of active vibration attenuation systems in the presence of unknown narrow band disturbances. The proposed methodology consists in two algorithms based on the Internal Model Principle. The first one deals with an indirect adaptive control, the second one with a direct adaptive control. The feasibility of the two algorithms is illust...

Voltage Control of Three Phase Inverters by Using Active Disturbance Rejection Control

Control of three phase inverters has been an important issue in recent years. This paper proposes active disturbance rejection control (ADRC) scheme for controlling three phase inverters. The main advantage of ADRC that motivated us for using this controller for inverter is that it is model independent.  This controller is used in a double loop structure including an inner current loop and oute...

Control Study of Precision Giant Magnetostrictive Actuator Based on Active Disturbance Rejection Control Technology

Introduce the structure and working principle of precision giant magnetostrictive actuator and establish the actuator system object transfer function model so as to design a suitable active disturbance rejection controller (ADRC). According to the model analysis, regard the actuator system as a first-order inertia object with dead time to construct second-order ADRC, use MATLAB for parameter tu...

Active disturbance rejection control: Theoretical perspectives

This paper articulates, from a theoretical perspective, a new emerging control technology, known as active disturbance rejection control to this day. Three cornerstones toward building the foundation of active disturbance rejection control, namely, the tracking differentiator, the extended state observer, and the extended state observer based feedback are expounded separately. The paper tries t...
