Research on Mized Scheduling Algorithm in Industrial Process Networked Control Systems
Based on the comprehensive scheduling index, a mixed scheduling algorithm is proposed for the problem that periodic tasks and non-periodic tasks share network resources in industrial process networked control systems.A network QoS estimator is used to acquire current network states. In order to improve the network operational performance, mixed scheduling algorithm is adjusted on-line according to the current network status and comprehensive scheduling index. Both the mechanism analysis and simulation show that this algorithm has great real-time performance, low network packet loss and high average performance.
