This paper discusses novel structure of communication disturbance observer (CDOB) to deal with time delayed controlled system. CDOB works based on the concept of network disturbance which considers the effect caused by time delay as one kind of force disturbance and estimate its value using disturbance observer (DOB). From estimated network disturbance force, time delay is compensated to maintain...
This paper presents the effectiveness of a time-delay compensation method based on the concept of network disturbance and communication disturbance observer for bilateral teleoperation systems under time-varying delay. The most efficient feature of the compensation method is that it works without time-delay models (model-based time-delay compensation approaches like Smith predictor usually need time-delay...
This paper proposes a novel structure of time delayed control systems with communication disturbance observer (CDOB). Time delay problem is one of difficult issues in control engineering and the effects seriously induces performance deterioration and destabilization. Therefore, many kinds of time delay compensation methods or stabilization methods have been proposed so far. As one of those methods,...
This paper presents stability analysis and a novel design method of time delayed control systems. The time delayed control systems are constructed based on a time delay compensation method using the concept of network disturbance and communication disturbance observer. At first, the effect of time delay in control systems is described briefly and the effectiveness of the time delay compensation method...
Time delay in bilateral teleoperation systems seriously deteriorates the performance and possibly affects the stability. A novel time delay compensation method based on the concept of network disturbance (ND) and communication disturbance observer (CDOB) has been proposed and the validity has been verified by simulation and experimental results so far. However the validity of the time delay compensation...
In any physical systems, there inevitably exists time delay. Since it has very characteristic and distinctive properties, control of time delayed systems is even now a very difficult and unresolved problem. Therefore a lot of researches about time delay have been studied so far. A distinguished time delay compensation method is Smith predictor. It can equivalently eliminates time delay from closed...
Time delay in bilateral teleoperation systems is inevitable and very serious problem. It possibly destabilize systems and deteriorates the performance of systems. Many researches about time delay in bilateral teleoperation systems have been proposed so far. In such a situation, authors have proposed a time delay compensation method based on the concept of network disturbance (ND) and communication...
In a research area of bilateral teleoperation systems, time delay generated in communication line is one of very serious problems. Time delay in control systems induces severe phase delay. Then the phase delay possibly destabilizes the system and deteriorates performance of the system. Therefore many studies about time delay in bilateral teleoperation systems have been conducted so far. Some researches...
