The invention relates to the technical field of motor control synchronization, and provides a multi-motor adaptive control synchronization system and method. The system comprises a main controller, asignal analysis device, and a plurality of motor assemblies. Each motor assembly comprises a driver, a motor and a vibration sensor; the control end of the main controller is electrically connected with the input end of the signal analysis device through the driver, the motor and the vibration sensor in sequence; and the output end of the signal analysis device is electrically connected with the input end of the main controller. The signal analysis device is used for respectively processing the vibration signals detected by the vibration sensors and transmitting the vibration signals to the main controller; and the main controller calculates the processed vibration signals to obtain the corresponding rotation state of the motor and the current required for synchronization, and sends the current required for synchronization to the corresponding driver. According to the invention, the plurality of electronic components are connected through the main controller and the signal analysis device, so as to observe the synchronization state of the motors, and adjust the synchronization state of the two motors or even the plurality of motors as required.
Description
technical field [0001] The invention relates to the technical field of motor control synchronization, in particular to a system and method for multi-motor self-adaptive control synchronization. Background technique [0002] Multi-pile hammer linkage technology is a technology that combines multiple pile hammers to drive piles. This technology solves the problem of low power of a single vibrating pile hammer, and synchronous control is one of the effective ways to realize multi-pile hammer linkage. one. Vibratory pile drivers and other machines that require multi-motor linkage put forward higher requirements for the synchronization of the speed and torque of the two motors. Effective control synchronization methods can improve the control accuracy and reliability of the system. [0003] At present, the control synchronization scheme for the flexible connection system in engineering is mainly the synchronous control of the motor speed. This scheme takes the consistency of the...
