Vibration feeder is commonly used in industrial automation control,and piezoelectric vibration bowl is the high?est efficiency and stability feeder,but there is an inefficiency problem caused by resonance point changes during its use. To solve that problem,an adaptive controller for piezoelectric vibration bowl is designed,which can continuously adjust the frequen?cy and amplitude of the piezoelectric vibration bowl. The fuzzy PID control makes amplitude of vibration bowl stable and the adaptive algorithm keep vibration bowl working in the best frequency. A quasi?resonant switching power supply is adopted in the controller to eliminate the effects of voltage fluctuations on the system. Design results show that the controller has a steady work performance,high efficiency and small drive noise.
