摘要
在建立系统模型的基础上,用输入输出特性相近的虚拟设备系统来实时仿真被控对象,以检验控制器的控制效果,达到减少现场调试、提高控制器安全性、改进控制效果等目的.给出了以TI公司TMS320F240DSP芯片为核心的虚拟设备系统的软硬件设计,并通过应用实例验证了虚拟设备的仿真效果.
With the development of the computer technology and digital signal processing technology, virtual technology has become popular. Application of virtual technology in control domain is called virtual device. To verify the effect of the controller, on the basis of system model, the virtual device with approximate input-output characteristics is employed for the system's real-time simulation, achieving the aim of reducing on-spot debugging, enhancing controller's security and improving effect. This paper presents hardware and software designs of a virtual device using DSP chip-TMS320F240, TI Com. and verifies the simulation effect of virtual device through application example.
