Undergraduate Controls Experiences Laboratory

当今的多输入/多输出机器人、制造、航空航天等过程的控制需要现代控制算法和多通道数字信号处理器(DSP)。让本科生参与一些有关数字信号处理器实时数字控制的实验经验是非常重要的。然而，在一门实验课程中很难学习基本的控制实现以及数字信号处理器的编程和结构。UTA自动化和机器人研究所(ARRI)正在开发的一个项目可以实现TI公司的TMS320 C30 DSP与LabVIEW软件的无缝集成。目前，DSP接口不是无缝的，但需要学习LabVIEW和DSP操作-这在一个学期的实验室课程中是不可能的。ARRI DSP/LabVIEW接口将允许LabVIEW用于实时控制，就像它在信号处理中一样，并将提供给全国的机构。它将允许将数字信号处理器视为运算放大器现在被处理在连续时间控制中，从而可以在不知道其操作细节的情况下使用该设备。数据传递、采样等过程将作为虚拟仪器(VI)驻留在LabVIEW中。在实验室课程中，控制器VI由用户选择并设置其系数。在项目实验室中的高级使用允许通过编写简单的C程序来实现复杂的控制算法，而不必担心DSP协议。ARRI最近得到了德克萨斯州ATP拨款的资助，用于开发DSP/LabVIEW接口。这笔ILI拨款将允许通过购买四个MAC/LabVIEW工作站将该技术移植到一个本科生控制实验室原型中。

Control of today's multi-input/multi-output robotic, manufacturing, aerospace, etc., processes requires modern control algorithms and multichannel digital signal processors (DSP). It is important that undergraduates participate in some laboratory experiences in DSP real-time digital control. However, it is difficult to learn basic controls implementation as well as the programming and structure of DSPs in one laboratory course.A project being developed at the UTA Automation and Robotics Research Institute (ARRI) allows seamless integration of the TI TMS320 C30 DSP with Labview software. Currently the DSP interface is not seamless, but requires one to learn Labview as well as the DSP operation - this is not possible in a one semester laboratory course.The ARRI DSP/Labview interface will allow Labview to be utilized in real-time controls as it has been in signal processing, and will be available to institutions nationwide. It will allow the DSP to be treated as the operational amplifier is now treated in continuous-time control, making it possible to use the device without knowing the details of its operation. The data passing, sampling, etc., processes will reside as virtual instruments (VI) in Labview. In a laboratory course, the controller VI is selected and its coefficients set by the user. Advanced use in a project laboratory allows the implementation of sophisticated control algorithms by writing simple C programs without worrying about the DSP protocol. ARRI was recently funded by a Texas ATP grant to develop the DSP/Labview interface. This ILI grant will allow porting of that technology to a prototype undergraduate controls laboratory by purchase of four MAC/Labview stations.
