Controller design for delay-independent stability of linear time-invariant vibration systems with multiple delays ☆

摘要: Abstract One of the critical parameters that can deteriorate effectiveness active vibration control (AVC) is delay in sensors. Especially, remote sensing where delays are large, and high-speed applications with even small delays, instability be inevitable. This paper presents algebraic approaches to design controllers order achieve stability regardless amount for AVC modeled by linear time-invariant systems “multiple” constant delays. The based on a nonconservative framework, identify regions controller gain space delay-independent (DIS) achievable. With these controllers, we demonstrate via simulations suppression, within certain excitation frequency bands, improved or as effective those without
