摘要 已有NCS仿真平台采用单一的全数字仿真或半实物仿真方式,在灵活性或真实性方面具有一定的局限性。首先归纳理想NCS仿真平台所应具有的品质,然后以其为指导提出了一种新的NCS仿真平台的实现框架,并基于MATLAB、OPNET、VisualC++等软件平台和软件组件设计思想实现了仿真平台NCS-SP(NCS-SimulationPlatform)。NCS-SP突破时延小于一个采样周期的限制,提供不同模块的多种选择属性,从而克服已有平台的不足,增强了仿真平台的有效性和灵活性。最后,通过不同网络环境下的仿真试验分析了网络时延和丢包对系统性能的影响。 The existent simulation platforms adopt either full digital simulation or simulation with some real elements in the loop, and therefore they have some disadvantages in flexibility or validity. The properties of an ideal NCS simulation platform were summarized and a novel framework for it was proposed, and then NCS-SP was implemented based on MATLAB, OPNET. Visual C++ and component technology. For NCS-SP, network delay can be more than one period and each part of NCS has some optional properties. It overcomes some disadvantages of existent simulation platforms and is more effective and flexible. Finally, the effects of the network delay and packet dropout to the performance of NCS were obtained through a series of simulation on NCS-SP.
