Robust active noise control in a car cabin: Evaluation of achievable performances with a feedback control scheme

“…Moreover, the attenuation must be obtained not at some isolated frequencies but over a (wide) frequency range. The authors previously proposed a single-input single-output (SISO) robust multi-objective ANC control synthesis in [13] and an overall methodology to compare the best achievable performances according to the number of sensor(s) and actuator(s) used [14]. The current paper pursues the latter objective by considering the needs of the automotive industry, using only feedback and exploiting the available microphones and loudspeakers.…”

“…Thus, a feedback controller will contain dynamics outside the target frequency range and the system behavior must be known over a wide range, which unfortunately results in high order models. As in [13,14], the subspace method is used to obtain a continuous time model from frequency domain data (see [23,24] for details on the corresponding identification algorithm). The authors also tested some alternative approaches such as the one based on Loewner matrices [25].…”

Exact noise cancellation for 1d-acoustic propagation systems

“…This model is inspired from the experimental setup already used in [4,5,21,22], and is schematized in Figure 1. Specifically, this experimental setup it is an elongated cavity.…”
