Active disturbance rejection control: Theoretical perspectives
نویسندگان
چکیده
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 to present relatively comprehensive overview about origin, idea, principle, development, possible limitations, as well as some unsolved problems for this viable PID alternative control technology.

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...

متن کاملActive Disturbance Rejection Control for Rejecting Boundary Disturbance from Multidimensional Kirchhoff Plate via Boundary Control
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 ...

متن کاملAn Active Disturbance Rejection Control Solution for Electro-hydraulic Servo Systems
The intriguing history of disturbance cancellation control is reviewed in this thesis first, which demonstrates that this unique control concept is both reasonable and practical. One novel form of disturbance cancellation, ADRC (Active Disturbance Rejection Control), attracts much attention because of its good disturbance rejection ability and simplicity in implementation. Hydraulic systems ten...
