Within civil engineering, the inclusion of control strategies is confined to limited application areas due to the practical overhead and an alleged conservatism. This paper presents a simple yet flexible framework for experimental testing of closed-loop structural systems. Compared to alternative existing solutions, the proposed framework requires limited programming knowledge, which heavily simplifies the implementation for the operator and thus reduces the associated practical overhead. The feasibility of the framework is demonstrated through two experimental case studies in which control strategies are used to, respectively, design and implement a hybrid tuned mass damper (TMD) and conduct closed-loop model updating. The case studies exemplify the diversity of control applications within civil engineering, and it is noted that while hybrid TMDs are used in the civil engineering industry, limited experimental application studies exist on closed-loop model updating of structural systems. It is concluded that the presented framework can be applied to cover a variety of structural control applications within civil engineering and the successful implementation of the framework in the two case studies highlights the benefits of feedback control within these applications.

用于结构控制应用的闭环实验测试框架

在土木工程中，由于实际开销和所谓的保守主义，控制策略的包含仅限于有限的应用领域。本文提出了一个简单而灵活的框架，用于闭环结构系统的实验测试。与现有的替代解决方案相比，所提出的框架需要有限的编程知识，这大大简化了运营商的实现，从而减少了相关的实际开销。通过两个实验案例研究证明了该框架的可行性，其中控制策略分别用于设计和实现混合调谐质量阻尼器 (TMD) 并进行闭环模型更新。案例研究举例说明了土木工程中控制应用的多样性，值得注意的是，虽然混合 TMD 用于土木工程行业，但在结构系统的闭环模型更新方面存在有限的实验应用研究。得出的结论是，所提出的框架可用于涵盖土木工程中的各种结构控制应用，并且该框架在两个案例研究中的成功实施突出了这些应用中反馈控制的好处。
