Composite control method of DC motor based on speed feedback
Gong-kuang zidonghua, 2013 In view of problems of slow response speed and bad anti-disturbance ability existed in traditional control system of DC motor, the paper proposed a composite double-loop control method of DC motor based on disturbance observer and speed observer.

Disturbance Observer-Based Frequency Regulation for Shipboard Microgrid With Communication Delay
IEEE Access, 2023 Load frequency control of power systems is inherently a disturbance rejection issue. This paper proposes a disturbance observer-based frequency regulation approach for a shipboard microgrid system with communication delay.

Experimental External Force Estimation Using a Non-Linear Observer for 6 axes Flexible-Joint Industrial Manipulators [PDF]
, 2013 This paper proposes a non-linear observer to estimate not only the state (position and velocity) of links but also the external forces exerted by the robot during Friction Stir Welding (FSW) processes.

High Gain Disturbance Observer and Its Application in Robust Control Attenuation [PDF]
, 2013 High gain observer (HGO) has been proved to be a good method to estimate states of Lipschitz nonlinear systems. In this paper, we focus on the HGO based external input (disturbance) estimator and disturbance attenuation control scheme.

Simple disturbance observer for disturbance compensation
IET Control Theory & Applications, 2010 Disturbance observer (DOB) without using additional sensors is an attractive method to attenuate the effects of disturbances as they are highly cost effective. This study proposes a simple form of DOBs, which does not need to solve the plant model inverse, and uses H∞ control method to design the Q-filter in the DOB.
