| Outline of Final Research Achievements |
This research is concerned with synthesis and analysis of tele-operation systems using communication networks with random delay. The effect of the random delay of the networks can be rewritten into the additive observation noise representation by using the Taylor expansion method to the observation system. The probability density function of the random delay in communication networks is assumed to be log-normal distributions. Introducing this expression, state estimation problem of tele-operation system with random delay of the communication networks is considered as a state estimation problem based on the nonlinear observation system with additive random delay noise. In this research, the bilateral control system using proposed state estimation method based on the observation data with random delay is considered. Two proposed state estimator is used for the reduction of effect of random delay in the communication networks. The proposed system shows good performance in this research.
