Centralised and decentralised configurations for panels with piezoelectric actuators
conference paper
This paper discusses configurations for controlling broadband noise using piezoelectrically excited panels. The configurations can be distinguished by the physical layout and by the control structure. The physical layout of the system has some influence on the complexity of the control algorithms. For particular actuator/sensor combinations and a particular control objective, the control architecture can be decentralized, using very simple feedback or feedforward controllers, at small performance loss when compared to a centralized architecture. For some applications that require a different control objective, an additional centralized or possibly distributed architecture could be beneficial. A hardware realization with an associated control framework that allows the implementation of such a combined centralized-decentralized architecture is shown. Examples that are given are an embedded central control unit with all electronics in a single module and a centralized-decentralized architecture with partly decentralized hardware that is integrated with structural parts.
