| Abstract: | ControlNet is adopted in networked control system based on token protocol.Aimed at the time-varying characteristics of net-worked delays,a method of on-line delay evaluation is proposed.The control parameters of LQR controller are adjusted along with the e-valuated delays.Then,apply parallel computation arithmetic to improve resource utilization,so that sampling rates can be increased and control performance can also be improved. |
