摘要
Based on the analysis of major factors that influence Networked Control Systems (NCSs) communication scheduling, a dynamic priority scheduling scheme based on fuzzy logic is presented. In the scheme, the communication priority is determined by 3 factors, which are the message deadline, the performance criterion and the parameter error of control loops. Experiments of medium access control (MAC) with CAN bus prove that the proposed dynamic priority scheduling can satisfy real-time demands of different control loops under heavy burden of network and improve the network utilization efficiency and NCSs' performance.
