This article focuses on the vibration reducing and angle tracking problems of a flexible
unmanned spacecraft system subject to input nonlinearity, asymmetric output constraint, and …

Robots with coordinated dual arms are able to perform more complicated tasks that a single
manipulator could hardly achieve. However, more rigorous motion precision is required to …

This paper outlines the vibration reduction of a spacecraft with flexible appendage subject to
external disturbances. The hybrid dynamic model of the spacecraft is described by both …

This article demonstrates the realization of angle tracking and deformation suppression by
developing two boundary controllers for a flexible variable-length rotary crane arm with …

The uncertainty and disturbance estimation (UDE)-based robust control strategy is able to
achieve good robust performance by estimating and compensating the uncertainty and …

This paper investigates the stabilization of a class of chaotic systems with both model
uncertainty and external disturbance. By combining the dynamic feedback control method …

This paper presents the precision motion control of a piezoelectric nanopositioning stage
using a new scheme of adaptive sliding mode control with uncertainty and disturbance …

In this paper, a new robust control strategy based on a predictor and the uncertainty and
disturbance estimator is developed for a class of uncertain nonlinear systems with …

In this technical note, the active disturbance rejection control (ADRC) is generalized to
uncertain nonaffine-in-control nonlinear systems. The proposed controller incorporates both …

Although wind power has gained tremendous development in recent years, how to achieve
mechanical loads optimization to extend service life-time of wind turbines is still a hot and …
