Nonlinear Extended State Observer Based on Output Feedback Control for a Manipulator With Time-Varying Output Constraints and External Disturbance

open access: yesIEEE Access, 2019
This paper presents an adaptive output feedback control for a manipulator under the presence of the time-varying output constraint and uncertainties. The proposed control is formulated based on a nonlinear extended state observer and a barrier Lyapunov ...

Contact-Aided Invariant Extended Kalman Filtering for Legged Robot State Estimation

open access: yes, 2018
This paper derives a contact-aided inertial navigation observer for a 3D bipedal robot using the theory of invariant observer design. Aided inertial navigation is fundamentally a nonlinear observer design problem; thus, current solutions are based on ...

Global Finite-Time Attitude Consensus of Leader-Following Spacecraft Systems Based on Distributed Observers

open access: yes, 2017
This paper addresses the leader-following attitude consensus problem for a group of spacecraft when at least one follower can access the leader's attitude and velocity relative to the inertial space.

Extended State Observer-Based Sliding-Mode Control for Three-Phase Power Converters [PDF]

open access: yes, 2017
This paper proposes an extended state observer (ESO) based second-order sliding-mode (SOSM) control for three-phase two-level grid-connected power converters. The proposed control technique forces the input currents to track the desired values, which can
