Experimental Evaluation of Disturbance Observer-based Vibration Suppression and Disturbance Rejection Control in Torsional System

Abstract. In the resonance ratio control, the estimation speed of the disturbance observer should have been much faster than the resonance frequency of the controlled system. However, too fast disturbance observer causes implementation problem. In this paper, we give the optimal speed of the disturbance estimation and propose a novel technique, slow resonance ratio control, which enables us to ...

Reduced order disturbance observer for discrete-time linear systems

In the paper, an output-based disturbance observer of reduced order is presented for a class of discretetime linear systems. First, a general form of a disturbance observer is proposed when full states are available. Then, by combining a state function estimator of minimal order, an output-based disturbance observer is derived. The existence condition will be formulated in the form of a static ...

Passivity Based versus Disturbance Observer

Disturbance Observer based robot control algorithms provide good performance while giving a straightforward method of gain selection. Unfortunately, the stability of these algorithms has not been shown rigorously for nonlinear systems such as robots. This paper demonstrates that a disturbance observer based algorithm can be made equivalent to the well known passivity based approaches of Sadegh ...

Design of EDFA Gain Controller based on Disturbance Observer Technique

Based on a theoretical erbium-doped fiber amplifier (EDFA) model, we have proposed an application of disturbance observer(DOB) with proportional/integral/differential(PID) controller to EDFA for minimizing gain-transient time of wavelength -division-multiplexing (WDM) multi channels in optical amplifier in channel add/drop networks. We have dramatically reduced the gain-transient time to less t...

Disturbance Observer Design for Robotic and Telerobotic Systems

Employing disturbance observers is an effective way of enhancing the stability and performance of the control systems subject to disturbances. Disturbance observers have been extensively used for control of mechatronic systems since their introduction in the 1980s. This thesis studies the design of nonlinear disturbance observers for robotic manipulators and their applications in the control of...
