“…Due to the reduced complexity and better feasibility for hardware implementation of multi-channel control systems, the decentralized control technique has been widely used [37][38][39][40][41][42][43][44][45]. To compensate the performance loss, a recent research proposed a method that properly chooses a so-called eigenvalue matrix so that a two-channel decentralized ANC system achieves the same noise reduction performance as the centralized one with guaranteed convergence [44].…”

“…The decentralized control strategy could be generalized to a system with more channels and different gradient searching methods [40]. Experiments using a decentralized active control system to reduce the vibration of a plate have been carried out in [43]. To compensate the instability caused by decentralized structure, a digital phase lag compensator has been designed.…”

Active noise control (ANC) systems usually involve a large number of loudspeakers and error microphones in order to achieve noise reduction over an extended region of space. Although fundamentals of ANC theory and principles of ANC methods have been well-established over the past 40 years, applications of this technology are facing new challenges. A larger quiet zone with better noise reduction performance is always desirable in a variety of real-life scenarios. This paper presents several important factors that affect the performance of multichannel ANC systems in some popular applications such as windows with natural ventilation and quiet-zone around heads. The factors affecting acoustic design include the reflection of a baffle plate, arrangement of error sensors in open areas, and so on. In addition, different control strategies are compared and analyzed, including centralized, decentralized, and distributed strategies. All these strategies are discussed from the signal processing side, which should be considered after a proper acoustic design. One of the important aims of this paper is to provide practical guidance for acoustic design and discuss several typical control strategies for multichannel ANC systems.

“…The method has been successfully tested for a solar power satellite. In Yu et al, 20 there was proposed a decentralized controller to mitigate the vibration of a plate. The control functions are derived based on the method of virtual absorbed energy, which enables establishing an optimal gain in the local velocity feedback control.…”

The problem of decentralized semi-active stabilization of vibration of a beam structure is studied. The decentralized controller's architecture is attained by means of optimal system modelling. In this approach, based on a specially designed and optimized set of basis functions, the solution to the continuous Euler-Bernoulli beam equation is approximated by a discrete system, where the mass and stiffness matrices ensure that the assumed stabilizing control law can be operated by using solely the local state information. The performance of the method is examined through numerical experiments for a series of free-vibration scenarios with comparison to competitive decentralized and centralized control strategies. The performance impact of the selection of the parameters of the optimal system model is also studied. The designed method allows practical modular arrangements of the control system and is applicable to large-scale structures.
