A new scheduling for networked control systems with limited resources

For the multi-loop networked control systems with limited resources, this paper puts forward a new scheduling method. The method directly bases on the two control performance parameters: error and error change rate. Combined with human-simulated intelligent thoughts, by setting deadband in the controller, and shows the new scheduling method´s advantages from theory analysis. Finally do simulation with truetime 1.5. This method makes the data on the network throughput significantly reduced and eases the burden of network; the control performance is significantly improved. Meanwhile, the scheduling method is also adapted to the strong interference environment.
