本文提出了一种基于LabVIEW的嵌入式控制系统快速原型平台设计。该设计采用基于嵌入式系统和PXI总线控制器的通信、驱动、反馈板卡搭建了数据接口层系统硬件。同时,基于LabVIEW、Simulink和VeriStand环境开发了模型实时仿真层软件系统,构成了快速原型平台的虚拟控制器。基于该平台,可以将设计的算法模型下载至实时虚拟控制器中运行,在实际控制器开发完成之前就可以考察控制算法的性能,有效缩短研制周期。该快速原型平台具有实时性好、可移植性高等优点,方便用户进行建模、设计和仿真工作,可广泛应用于各类嵌入式控制系统中。

In the paper,a rapid prototyping platform for embedded control systems based on LabVIEW is proposed.The design uses the communication,drive and feedback board based on embedded system and PXI bus controller to build the data interface layer system hardware.Meanwhile,the model real-time simulation layer software system is developed based on LabVIEW,Simulink and VeriStand environment,which constitutes the virtual controller of the rapid prototyping platform.Based on this platform,the designed algorithm model can be downloaded to the real-time virtual controller,and the performance of the control algorithm can be inspected before the actual controller is developed,which effectively shortens the development period.The rapid prototyping platform has the advantages of high real-time performance and high portability,which is convenient for modeling,design and simulation work, and can be widely used in various embedded control systems.
