ENGINEERING RESEARCH EQUIPMENT: A Real-Time Processor and Diagnostic Equipment for Closed-Loop Control Experiments

9310735伯恩斯坦密歇根大学航空航天工程系将购买一台实时控制处理器和相关诊断设备，专门用于支持控制系统工程的研究。该设备将用于几个研究项目，特别包括：不稳定工厂的控制、执行器约束的控制、旋转航天器的控制、声波振动的控制、柔性结构的控制以及流体的控制。控制系统技术是许多复杂、高性能系统的使能技术。在许多这样的应用中，控制系统是如此重要，以至于系统没有它就不能运行。另一方面，控制系统的故障可能会产生可怕的后果。生动的例子包括切尔诺贝利灾难和空客坠毁。鉴于控制系统技术的重要性和风险，本提案寻求实验室设备的形式或实时控制处理器和相关诊断设备，以使研究人员能够在反馈控制技术方面进行广泛的实验。拟议的实时处理器是进行闭环控制实验所需的核心设备。利用这种设备，可以将用高级语言表示的新的控制律转换成实时汇编代码，以便高速执行。这一能力将使研究人员能够实现针对各种应用而设计的线性和非线性控制器。在将利用该设备的项目中，有两个项目侧重于反馈技术中的基本问题，即不稳定对象的控制和具有执行器约束的控制，以及四个侧重于具体应用的项目，即航天器、声学、结构和流体的控制。***

9310735 Bernstein The Department of Aerospace Engineering at the University of Michigan will purchase a real-time control processor and related diagnostic equipment which will be dedicated to support research in control-system engineering. The equipment will be used for several research projects, including in particular: control of unstable plants, control with actuator constraints, control of rotating spacecraft, control of acoustic vibration, control of flexible structures, and control of fluids. Control -system technology is an enabling technology for many complex, high performance systems. In many of these applications the control system is so essential that the system simply cannot operate without it. On the other hand, failure of the control system can have dire consequences. Graphic examples include the Chernobyl disaster and Airbus crashes. In view of the importance and risks of control-system technology, this proposal seeks laboratory equipment in the form or real-time control processor and related diagnostic equipment to allow researchers to carry out a broad range of experiments in feedback control technology. The proposed real-time processor is the central piece of equipment needed to carry out closed-loop control experiments. With this equipment, new control laws represented in a high level language can be transformed into real-time assembly code for high-speed execution. This capability will allow researchers to implement linear and nonlinear controllers designed for a variety of applications. Among the projects that will utilize the equipment are two projects that focus on fundamental problems in feedback technology, namely, control of unstable plants and control with actuator constraints, as well as four projects that focus on specific applications, namely, control of spacecraft, acoustics, structures, and fluids. ***
