摘要
数模混合仿真系统由实时数字仿真系统和物理仿真系统构成,并通过接口装置连接起来。分析了数模接口装置的基本要求,设计了接口装置的主电路结构和控制方案,并在MATLAB仿真平台下进行了接口装置的仿真验证。仿真结果表明接口装置可以很好地实现电压或电流的跟踪,能够满足数模混合仿真系统的要求。
A digital-analog hybrid simulation system consists of two subsystems： a real-time digital simulation system and a physical simulation system, which are connected with an interface device. This paper analyzes the basic design requirement of digital-analog interface, and designs the main circuit structure and control program. Simulations of the design are carried out with the MATLAB, and the results indicate that the interface device can realize voltage or current tracking well, meeting the requirements of digital-analog hybrid simulation system.
