基于Simulink的混合试验系统及其验证

作为混合模拟的工具，目前的混合试验系统向分布式复杂化发展，这不便初学者理解混合模拟的执行过程，也分散了研究者集中研究的精力，为此本文研究了基本的混合试验系统。首先介绍了Matlab中的Simulink仿真环境，然后提出了基于Simulink的混合试验系统，并讨论了混合模拟执行中的关键问题。最后分别利用简化的加载系统模型和真实的加载系统进行了混合试验系统仿真与验证。仿真结果表明所提混合试验系统各模块可协同工作；试验结果表明该混合试验系统便于进行硬件在回路仿真。

Simulation and Validation of Hybrid Testing System Based on Simulink

As the tool of Hybrid Simulation(HS), Hybrid Testing System(HTS) is developing toward distributed and complex direction. It is difficulty for the beginners to understand the process of HS and for the researchers to focus on a particular field. Herein a basic HTS is studied. Firstly, Simulink simulation environment is introduced. Then, the basic principle of HS and the framework of HTS is elaborated, A HTS based on Simulink simulation environment is proposed, and some key problems in HS are discussed. Finally, HTS simulation and validation are carried out using a simplified loading system model and a real loading system respectively. The results indicate that the modules of the HTS can work together and it can easily implement hardware in the loop simulation.
