Engineering Research Equipment: Instrumentation for an Experimental Control Systems Laboratory

9729290bernstein控制系统技术是许多复杂的高性能系统的使能技术。在许多这些应用中，控制系统是如此重要，以至于没有它系统根本无法运行。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机事件。近年来，很明显，控制研究人员面临的主要挑战之一是需要将理论进展转化为操作系统。为了应对这一挑战，我提议通过扩展现有实验和开发新实验来扩大我的控制实验室。这些实验为理论控制概念提供了动力，并有助于控制理论向实践的过渡。在NSF的前期支持下，我们开发了5个控制实验，分别是声道实验、旋转致动器实验、旋转不平衡实验、控制力矩陀螺实验和自主飞行器实验。根据拟议的计划，所有这些实验都将扩展以增加其通用性并提供额外的挑战。此外，我们建议进行三个额外的实验，即三维声场的控制，膜的静电控制和燃烧的控制。这些额外的实验为我们之前的实验活动提供了一个重要的扩展，进入新的和更具挑战性的控制应用。根据这笔拨款购买的设备包括一个高速实时并行处理器以及支持基础设施，包括传感器、执行器、滤波器、放大器和电源。＊＊＊

9729290BernsteinControl-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 recent years it has become clear that one of the principal challenges facing control reseaxchers is the need to transition theoretical advances to operational systems. To address this challenge, I am proposing to expand my control laboratory by extending current experiments and by developing new experiments. These experiments provide motivation for theoretical control concepts and help to transition control theory to practice.Under prior NSF support we have developed five control experiments, namely, the acoustic duct experiment, the rotating actuator experiment, the rotating imbalance experiment, the control-moment gyro experiment, and the autonomous aircraft experiment. Under the proposed program all of these experiments will be extended to increase their versatility and to provide additional challenges. In addition, we propose to develop three additional experiments, namely, control of three-dimensional acoustic fields, electrostatic control of a membrane, and control of combustion. These additional experiments provide a significant expansion of our prior experimental activities into new and more challenging applications of control.The equipment to be purchased under this grant includes a high-speed real-time parallel processor along with supporting infrastructure which includes sensors, actuators, filters, amplifiers, and power supplies. ***
