Disturbance-Compensation-Based Continuous Sliding Mode Control for Overhead Cranes With Disturbances
IEEE Transactions on Automation Science and Engineering, 2020For practical mechanical systems, uncertainties/disturbances, such as unmodeled dynamics and frictions, are nonignorable factors. For existing control methods, these factors are usually neglected or addressed by a robust way.

The Disturbed and the Disturbing Psychiatric Resident
Archives of General Psychiatry, 1976Two hundred psychiatric residents who were in training during a 25-year period were retrospectively studied. We found that residents could be meaningfully divided into the four following categories: (1) neither disturbed nor disturbing; (2) disturbed and disturbing; (3) disturbed but not disturbing; and (4) disturbing but not disturbed. There is a need

Communication Disturbances and Hyperactive/Conduct-Disturbed Behavior
Psychiatry, 1989This study examines mother-child communication as one factor in the development of conduct-disturbed/hyperactive boys. Three groups of school-age children were compared: a group including conduct-disturbed/hyperactive boys who had a significant insult in their perinatal/developmental history; a group of conduct-disturbed/hyperactive boys in whom no ...

Disturbance observers for constant disturbances
2019 16th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON), 2019The parameterization of linear disturbance observers for constant disturbances has been studied in this paper. By using the states and inputs of the system as variables, the parameterization under constant disturbances was obtained in frequency domain, the validity of the disturbance observer was proofed by simulation.

Boundary Disturbance Observer-Based Control of a Vibrating Single-Link Flexible Manipulator
IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2019This paper examines the boundary disturbance observer-based control for a vibrating single-link flexible manipulator system possessing external disturbances. Two new boundary anti-disturbance control strategies are presented to eliminate vibration, track

Intertemporal Disturbances [PDF]
, 2006 Disturbances affecting agents intertemporal substitution are the key driving force of macroeconomic fluctuations. We reach this conclusion exploiting the bond pricing implications of an estimated general equilibrium model of the U.S. business cycle with a rich set of real and nominal frictions.

A novel control scheme for quadrotor UAV based upon active disturbance rejection control
Aerospace Science and Technology, 2018A double closed-loop active disturbance rejection control (ADRC) scheme is proposed to deal with some difficult control problems in the quadrotor unmanned aerial vehicle (UAV) system such as nonlinearity, strong coupling and sensitive to disturbance, etc.

Tracking Flight Control of Quadrotor Based on Disturbance Observer
IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2019In this paper, a tracking flight control scheme is proposed based on a disturbance observer for a quadrotor with external disturbances. To facilitate the processing of external time-varying disturbances, it is assumed to consist of some harmonic ...
