The invention provides an AC servo driving method and device based on artificial intelligence. The method comprises the following steps: acquiring an alternating current servo motor control signal, and extracting an alternating current signal, alternating current signal generation time and alternating current servo motor control signal duration from the alternating current servo motor control signal; acquiring a local alternating-current electric signal calibration table, calibrating the alternating-current electric signal, and acquiring angular velocity or angular displacement according to the alternating-current electric signal when the calibration is passed; obtaining a local rotor control strategy table, and selecting a corresponding rotor control strategy from the local rotor control strategy table according to the duration of the alternating current servo motor control signal; and driving the alternating current servo motor according to the rotor control strategy, the angular velocity or the angular displacement. According to the invention, the alternating current servo is driven by setting different control strategies, and the control strategies are continuously updated in an artificial intelligence mode, so that the driving efficiency of the alternating current servo motor is improved, and the user experience is improved.
Description
technical field [0001] The invention relates to the technical field of computer software, in particular to an artificial intelligence-based AC servo drive method and device. Background technique [0002] The power supply device that controls and drives a general-purpose rotary AC servo motor is called an AC servo drive. The rotor inside the servo motor is a permanent magnet, and the U / V / W three-phase power controlled by the drive forms an electromagnetic field. The rotor rotates under the action of this magnetic field, and at the same time the motor The built-in encoder feedback signal to the driver, the driver compares the feedback value with the target value, and adjusts the angle of rotation of the rotor. The AC servo driver controls the motor through sine waves, and the torque ripple is small. [0003] The existing AC servo drive method needs to be improved in terms of the calibration of the AC signal and the control strategy. Therefore, an AC servo drive method based on...
