A nonlinear disturbance observer for robotic manipulators [PDF]

, 2000
A new nonlinear disturbance observer (NDO) for robotic manipulators is derived in this paper. The global exponential stability of the proposed disturbance observer (DO) is guaranteed by selecting design parameters, which depend on the maximum velocity ...

Functional Observer Design for Time-Delayed Systems With Application to Fault Diagnosis

IEEE Access, 2019
This paper deals with the functional observer (FO)-based fault detection and isolation problem for time-delayed linear systems. First, a new method to design the low-order FO estimating the partial states for linear systems with time-varying delay is ...

Input-Output Finite-Time Sliding Mode Control of Discrete Time-Varying Systems Under an Adaptive Event-Triggered Mechanism

IEEE Access, 2023
This paper is concerned with the issue of input-output finite-time stability (IO-FTS) for a class of nonlinear discrete time-varying systems. A time-varying observer-based sliding mode control method is proposed.

Parametric design to reduced-order functional observer for linear time-varying systems

Measurement + Control, 2021
This article studies the parametric design of reduced-order functional observer (ROFO) for linear time-varying (LTV) systems. Firstly, existence conditions of the ROFO are deduced based on the differentiable nonsingular transformation. Then, depending on
