Conventional active vibration control methodologies predominantly focus on achieving performance improvement relative to open-loop systems, rather than exploring the inherent performance boundaries imposed by physical constraints, system structures, and actuation/sensing limitations. To overcome these drawbacks, performance-limit oriented active control of vibration has emerged as a systematic design framework that aims at revealing and approaching the theoretical performance boundaries. This paper presents an overview of performance-limit oriented active vibration control from past developments, current advances, and future perspectives. Specifically, a major development in the field has been established with a “visualization technique” where performance limits can be readily determined solely based on visual inspection, yet resolving fundamental issues as existence, optimality, and performance limits of controllers, as well as evaluating the influence of constraints on optimal solutions. New developments are suggested for extensions to high-order heterogeneous complex networks, and particularly to adaptive and intelligent solutions, which enable online performance limit tracking, data-driven boundary estimation, and thus enhance robustness against uncertainties and nonlinearities. Future directions are prospected toward nonlinear performance-limit analysis and real-time computational methods under extreme conditions, and wider applications in high-end manufacturing, aerospace, and military equipment. This paper is expected to promote the in-depth development and engineering popularization of performance-limit oriented control theory and technology.
