Research on applying the extended state observer to model parameter identification for shared control systems

In order to realize the on-line estimation of shared plants' parameters in internet based shared control systems by the server node, the paper proposes a new method that can on-line identify the model parameters through an internet based shared control system under the time-varying and time-delay environment. By observing out all the model variables of shared plants in different states by the extended state observer in different region and utilizing the network technology, the method realizes the on-line identification of model parameters of the remote terminal. The numerical computer simulations were performed to compare the system' result with the existing systems without the influence of network factors, and the results show that the proposed method is valid and feasible, which can realize the identification of model parameters of the controlled objects in different regions under the network environment, and extend the applications of the on-line identification systems.
