Bandwidth scheduling strategy with deterministic time-constraint for networked control systems
In view of the periodical tasks and emergent tasks transmitted in networked control systems, a bandwidth scheduling scheme with deterministic time-constraint is proposed. Based on task demands analysis, the limited network bandwidth is allocated to each transmission task properly by dividing time-window, setting priority of tasks and the initial transmission moment of each task. As a result, delay jitter is reduced and network bandwidth is used reasonably, which can guarantee the quality of network service. Finally, the simulation study of dual-cylinder pushing synchronous control system shows the effectiveness of the proposed scheme.
