摘要
针对基金会现场总线(FF)系统,构建了基于MATLAB的周期性信息和功能块调度仿真平台,来评价实时信息调度算法的有效性和研究通信时延对系统控制性能的影响.介绍了周期性信息和功能块调度仿真平台的构建及其功能;应用调度仿真平台对分别采用扩展单调速率ERM算法和启发式算法构建的调度时间表进行评价和对比分析;通过仿真平台来研究通信时延和调度时间表对FF系统控制性能的影响.
The periodic messages and function blocks scheduling simulator based on MATLAB are developed to evaluate the real-time message scheduling methods and research into the effect of communication delay on control performance based on FF(Foundation Fieldbus)system.Firstly,the periodic messages and function blocks scheduling simulator are built and their functions are introduced.Secondly,the schedule time lists built by extend rate monotonic algorithm and heuristic algorithm are evaluated and comparatively analyzed,which is based on the simulator.Finally,the simulator is used to study the effect of communication delay and schedule time list on the control performance of FF system.
