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 is presented. Then analysis about the effects of parameters in control systems on stability of the time delayed control systems is analyzed. The main part of this paper is proposal of a novel design method of time delayed control systems according to the analytical results. Simulation results verify the validity of analytical results and proposed design method. The results also demonstrate the effectiveness of the time delay compensation method using the concept of network disturbance and communication disturbance observer.

Abstract
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 is presented. Then analysis about the effects of parameters in control systems on stability of the time delayed control systems is analyzed. The main part of this paper is proposal of a novel design method of time delayed control systems according to the analytical results. Simulation results verify the validity of analytical results and proposed design method. The results also demonstrate the effectiveness of the time delay compensation method using the concept of network disturbance and communication disturbance observer.Pubblicazioni consigliate
