Control of magnetic bearing having feedforward compensator.

IEEJ Transactions on Industry Applications, 1990
In the past, the controller of magnetic bearing was desined only by noticing the stability and robust property. However if the response of displacement by reference signal is implemented, some new industrial applications can be expected. Therefore, in this paper we propose a control method of magnetic bearing, and we especially take account of an ...

Finite‐Time Disturbance Observer‐Based Nonlinear Robust Adaptive Control of Hydraulic Manipulator With Parameter Identification

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Hydraulic manipulators exhibit strong coupling, pronounced nonlinearities, and significant modeling uncertainties, which hinder high‐precision motion control. This paper proposes a finite‐time disturbance observer–based nonlinear robust adaptive control (RAC‐FTDO) framework enhanced by a physically consistent dynamic parameter identification ...
