主动系统和自适应系统由具有不同功能的各种组件组成。随着系统复杂性的增加，可靠性和稳健性研究变得更加复杂。灵敏度分析有助于系统设计人员了解系统组件之间的相互作用，并确定对系统性能具有重大整体影响的重要参数。为了分析主动系统各部件和参数对系统性能的复杂相互作用，在实验室试验台上建立了具有主动减振的框架结构。利用该试验台进行了试验灵敏度分析，研究了系统部件和参数对减振效果的影响。采用自适应控制，使主动系统具有较强的鲁棒性。
Active and adaptive systems consist of various components with different functionalities. As the complexity of the systems increases, reliability and robustness studies become a more complicated task. Sensitivity analysis helps system designers to understand interactions between the system components and to identify the important parameters with significant overall influences on the system performance. To analyze the complex interactions of the components and parameters of an active system with respect to system performance, a framework structure with active vibration damping in a lab scale test rig was set up. With this test rig an experimental sensitivity analysis was performed to investigate the influences of the system components and parameters on the vibration reduction. A higher robustness of the active system was achieved by using adaptive control.
