[ES] El principal objetivo de este trabajo es comparar los resultados obtenidos al aplicar técnicas de Control Activo del Ruido (CAR) y de Control Activo Acústico Estructural (CAAE) a una placa simplemente soportada. En ambos casos la fuente de excitación es una piezocerámica. Como actuador se utiliza un altavoz y una piezocerámica del mismo tipo, en los dispositivos CAR y CAAE respectivamente. La unidad de control utilizada, que implementa los algoritmos FXLMS y FULMS, genera el campo secundario para reducir el ruido radiado por la placa.
[EN] The main objective of this work is to compare the results of applying Active Noise Control (ANC) and Active Structural Acoustic Control (ASAC) to a simply supported plate. In both cases the exciting source is a piezoceramic. As actuator, a loudspeaker and a similar piezoceramic are used in the ANC and ASAC systems, respectively. A control unity which implements both FXLMS and FULMS algorithms is used to generate the secondary field in order to reduce the noise radiated by the plate.
