Abstract

With adaptive band-pass filter to extract the work of the ultrasonic transducer fundamental base wave signal, to obtain the phase difference between current and voltage, then the fuzzy control method according to the phase displacement to achieve automatic frequency tracking (AFT), through the current control actuator output amplitude, so constant, accurate frequency tracking can be achieved to ensure that the quality ultrasound equipment and efficiency.
