|
摘要
实时混合试验是在拟动力试验技术的基础上发展起来的新型混合试验技术。域间并行多步长分离积分算法因能解决该技术中多步长协调问题、能提高积分计算效率而在实时混合试验中具有较好的应用前景。探讨了采用Simulink/嵌入Matlab函数模块执行复杂实时混合试验的可行性,归纳了该方法的优点,完成了基于一种并行多步长分离积分算法的实时混合试验。研究表明,该方法便捷可靠,为复杂实时混合试验提供了有效建模工具。
Real-time Hybrid Simulation(RHS),a novel hybrid testing method,is an extension of the pseudo -dynamic testing approach.Inter-field parallel multi-rate partitioned algorithms are promising in RHS due to their abilities of resolving compatibility problem of multi-sampling times and improving computation efficiency. This paper discusses the feasibility of complicated RHS implementation using Simulink/Embedded Matlab Function Block and summaries its advantages.Realistic RHS was carried out with an inter-field parallel multi-rate partitioned algorithm.The research shows that RHS with this block is convenient and reliable,which provides an effective tool for complicated RHS.
