针对控制网络中协议异构性以及通信环境不确定性的问题,提出可重构协议栈体系结构。基于MATLAB环境下的Stateflow和Simevents工具箱,设计了一套通用的协议元件库,支持协议栈静态重构和动态重构性能的仿真研究。进一步,研究了与Simulink工具箱的接口,实现协议栈与控制对象模型的联合仿真。该方法为研究协议栈对网络控制系统的影响提供了一个良好的平台,发展和完善了协议栈可重构理论。
To cope with the challenge of protocol heterogeneous and environment uncertainty in the control network,a reconfigurable architecture for the protocol stack was proposed.Under the MATLAB environment,mainly the toolbox-Stateflow and Simevents,a set of general protocol components was designed to support the simulation of the static and dynamic performance of reconfigurable protocol stack.Furthermore,the interface to the toolbox-Simulink was studied for the co-simulation of the protocol stack model and the control object model.The method was showed to be efficiency in evaluating the influence of protocol stack on the control system,and the theory of reconfigurable protocol stack was developed and improved.
