基于Modelica的多领域伺服系统的研究

Research on the Multi-domain Servo-system

在实际应用需求中,跨领域建模与仿真已经变得越来越普遍。面向对象物理建模语言Modelica使多领域建模变得相对简单,并能在完全支持Modelica语言环境下的Dymola平台上进行仿真。采用Mod-elica语言分别对开环伺服系统和半闭环伺服系统进行了建模,并在Dymola上仿真。仿真结果表明,多领域的伺服系统动态响应性能效果良好,与分析基本上吻合。利用Modelica语言的开放性,根据研究对象的需要建立一些相关的模型,同时也完善了模型库。Modelica/Dymola为伺服系统的研究提供了一种方法。

Multi-domain modeling and simulation has become increasingly widespread in practical demand.The object-oriented physical modeling language Modelica makes the multi-domain modeling relatively simple,and it could be simulated in the platform of Dymola which fully supports the Modelica language.Modeling and simulation of open servo-system and half-close servo-system is implemented in Modelica language under Dymola environment.Simulation results showed that multi-domain servo-system＇ dynamic performance was fine and identical to the practical analysis.Based on the openness of Modelica language,some relative models was created on the studied object＇ demand;Meanwhile,the library became more complete.Modelica/Dymola provides a way to investigate NC（Numerical Control） servo-system.
