Correção dinâmica de frequência de transdutores piezelétricos utilizando um sistema computacional inteligente

Dynamic frequency correction systems for piezoelectric transducers can be implemented using techniques with artificial intelligence. This paper presents preliminary results of the implementation of a system that adjusts the excitation frequency of a transducer from an intelligent search done in a preloaded database. The information retrieved from the database acts on the feedback loop of an oscillator. The results showed that the system is agile, robust, simple building and the hardware is low cost, besides the fact of the magnitude of the errors, the values are around 0.02 kHz, should not severely affect the performance of the system.
