| description | The invention discloses a vibration table power amplifier current automatic equalization control method and device. The method comprises the following steps: (1) acquiring and storing expected current and output current of each branch power amplifier; (2) performing power amplifier fault diagnosis by using historical data of expected current and output current in combination with instantaneous current, current accumulation relative error and current change rate relative error; and (3) dynamically distributing the current of each branch power amplifier according to the fault diagnosis result of the power amplifier. The current automatic equalization control device comprises a master console and branch slave control modules. According to the method, the operation condition information behind the current data is fully mined in the parallel driving process of the multiple power amplifiers, power module fault diagnosis under existing data is realized, the difference of the operation performance of each module is c |
