本文提出了第一代斜拉桥基准结构控制问题的问题定义。基准问题基于目前在密苏里州吉拉多角正在建设的比尔·爱默生纪念大桥。该桥预计将于 2003 年竣工。本研究的目的是为斜拉桥控制策略的制定提供一个试验平台。基于详细图纸，开发了一个三维评估模型来表示全尺寸基准桥的复杂行为。使用围绕变形平衡位置生成的运动方程开发线性评估模型。选择与斜拉桥地震响应控制目标一致的评价标准。控制约束确保结果代表物理结构上的控制实现。该基准研究的每个参与者都被赋予定义（包括设备、传感器和算法）、评估和报告其提议的控制策略的任务。这些策略可以是被动的、主动的、半主动的或它们的组合。提供了一个模拟程序，以便于直接比较各种控制策略的功能和效率。该问题可以通过互联网以一组 MATLAB(R) 程序的形式获得，其中包括一个示例控制设计，用于指导参与者解决基准问题。
This paper presents the problem definition for the first generation of benchmark structural control problems for cable-stayed bridges. The benchmark problem is based on the Bill Emerson Memorial Bridge that is currently under construction in Cape Girardeau, Missouri. Construction of the bridge is expected to be completed in 2003. The goal of this study is to provide a testbed for the development of strategies for the control of cable-stayed bridges. Based on detailed drawings, a three-dimensional evaluation model has been developed to represent the complex behavior of the full scale benchmark bridge. The linear evaluation model is developed using the equations-of motion generated around the deformed equilibrium position. Evaluation criteria are selected that are consistent with the goals of seismic response control of a cable-stayed bridge. Control constraints ensure that the results are representative of a control implementation on the physical structure. Each participant in this benchmark study is given the task of defining (including devices, sensors, and algorithms), evaluating, and reporting on their proposed control strategies. These strategies may be either passive, active, semiactive, or a combination thereof. A simulation program is provided to facilitate direct comparison of the capabilities and efficiency of the various control strategies. The problem is available through the internet in the form of a set of MATLAB(R) programs and includes a sample, control design to guide participants through the benchmark problem.
