摘要:Aiming at the issues of random delay and delay uncertainty in the control information network, a kind of network remote closed-loop control structure based on virtual reality is proposed. In accordance with the idea of open-loop system to achieve closed-loop control, this method focuses on constructing the virtual controlled object model in the client, making the virtual simulation system and the actual operation of the system state similar or even identical, and allowing the operator to decide the next control instruction which is according to the operation of the virtual simulation system at the same time. By this means, the required control instructions to the actual system is given accurately, which makes purpose of remote real-time control possible. Simulation results show that the structure of the remote control system obtains good dynamic quality and reduce the impact of network delay aspects to the system dynamics characteristics, which is a reference idea to the remote real-time closed-loop control.
