借助Simulink及ADAM模块构建半实物仿真系统

Implementation of Hardware-in-the-loop Simulation System Based on Simulink and ADAM Modules

针对基于Simulink的纯数字仿真难以精确模拟真实控制对象的现状,提出了一种实时半实物仿真系统的实施方案。该系统采用Simulink中的串行通信功能块及高性价比的ADAM-4000模块;系统利用ADAM模块构成现场接口,使用Simulink设计的控制器直接控制真实的被控对象,从而达到理想的控制器设计效果。该方案可为各种控制算法的研究和验证提供一个良好的实验平台,并能减少控制系统设计的开发周期和开发成本。

Purely digital simulation based on Simulink was often difficult to accurately simulate the real control object, thus the implementing strategy of real-time ＆ hardware-in-the-loop （ HIL） simulation system is proposed. The system is constructed with the serial communication functional block in Simulink, and coordinating with the high cost effective ADAM-4000 module. By adopting ADAM module, the field interface is built, and the real controlled object are direcly controlled by the controller designed with Simulink to achieve better design effect of the controller. The scheme provides excellent experimental platform for researching and verifying various control algorithms, and reduces the developing cycle and cost for control system design.
