Extended State Observer Based on ADRC of Linear System with Incipient Fault

International Journal of Control, Automation and Systems, 2019
Owing to the fact that it is difficult to find the incipient fault and it is hard to deal with the disturbance, an extended state observer (ESO), which is based on the linear time invariant system is designed and analyzed. This method can effectively separate incipient fault as a new state variable from the disturbance.

Formation control for nonlinear multi-agent systems with linear extended state observer

IEEE/CAA Journal of Automatica Sinica, 2014
This paper investigates the formation control problem for nonlinear multi-agent systems with a virtual leader. A distributed formation control strategy based on linear extended state observer (LESO) is proposed under the hypothesis that velocity of the agent's neighbors could not be measured.

On Convergence of the Linear Extended State Observer

IEEE International Symposium on Intelligent Control, 2006
Motivated by the gap between theory and practice in control problems, Linear Active Disturbance Rejection Control (LADRC) addresses a set of control problems in the absence of precise mathematical models. LADRC depends on the quick convergence of a unique state observer, known as the extended state observer, proposed by Han.

Optimal fast tracking observer bandwidth of the linear extended state observer

International Journal of Control, 2007
In current industrial control applications, the proportional + integral + derivative (PID) control is still used as the leading tool, but constructing controller requires precise mathematical model of plant, and tuning the parameters of controllers is not simple to implement.

Modified Extended State Observer Control of Linear Systems

AIAA Guidance, Navigation, and Control Conference, 2016
In this paper, a novel architecture for model following control of uncertain Linear Time Invariant (LTI) systems in case of state feedback is presented. The architecture is based on a Modified Linear Extended State Observer (MLESO), which estimates the disturbance signal that causes the real plant to deviate from the reference model.
