Control of Voicecoil transducers: Design and implementation of a Motional Feedback Loudspeaker Woofer

This master thesis describes the dynamical behaviour of a loudspeaker woofer and the modelling of it. By the use of the knowledge gained from the model, a feedback controller is implemented in order to enhance the woofer’s performance in terms of acoustic total harmonic distortion (THD) and low frequency bandwidth. The first objective of the...
