New continuous state observer design for networked visual servo control systems with variable delayed and sampled output

Abstract

This paper deals with the problem of observer design for networked visual servo control systems with time varying delayed and sampled output. The proposed observer called new continuous state observer is motivated by the communication disturbance observer which is proposed to solve the time delay problem. Different from the current work, this paper aimed at improving the communication disturbance observer and making it suitable for the case of delayed and sampled output. The proposed continuous state observer has a very simple structure and can be easily implemented. The stability of this observer is also analyzed and demonstrated. Finally, some simulation results are sketched to demonstrate significant performance improvement of the proposed observer.
