【Abstract】 In terms of the architecture of networked control systems with multi-control loops,a feedback scheduler is designed to implement the scheduling strategy.According to the requirement of control performance optimization,the system schedulability is analyzed.Control performances of networked control systems with multi-control loops can be optimized on-line by adjusting sampling periods of loops and using the priority assignments.The schedulable analysis and scheduling strategy are validated by the simulation of networked control systems with three control loops.更多还原
