Novel robust disturbance observer

ISA Transactions, 2020
In this paper, a predictive disturbance observer (DOB) design is presented. The proposed DOB does not require a direct model of the process without the transport delay for prediction purposes. The primary advantage of the proposed DOB design is its simplicity due to usage of the prediction block (PB), which approximates the ideal anticipation object ...

Recursive sliding mode control with adaptive disturbance observer for a linear motor positioner

, 2021
The control performance of linear motor (LM) is deteriorated by payload variations, friction, and external disturbances. In this paper, a robust recursive sliding mode controller combined with an adaptive disturbance observer (RSM-ADO) is proposed for ...

Disturbance observers for constant disturbances

2019 16th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON), 2019
The 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.
