Abstract

A multi-motor crossed synchronous control system and a control method therefor. The multi-motor crossed synchronous control system (10) comprises: a motor (20); a detection unit (30), a first detection input port (301) being provided at a power output port (202) of the motor (20); a motor control unit (40), a first control input port (401) being connected to an instruction source, a second control input port (402) being connected to a first detection output port (302), and a first control output port (403) being connected to a motor input port (201); and a vibration suppression control unit (50), an input port (501) being connected to a second control output port (404), and an output port (502) being connected to the motor control unit (40). The vibration suppression control unit (50) compensates the current of the motors (20), so that the vibration of multiple motors during high-speed running is avoided, and thus multi-motor synchronous control and stable running are implemented.

Description

technical field [0001] The present application relates to the field of motor control, in particular to a multi-motor cross synchronous control system. Background technique [0002] The main function of the motor is to generate driving torque as a power source for electrical appliances or various machines. With the continuous development of manufacturing, semiconductor, non-standard automation and other industries, a single motor drive can no longer meet the needs of modern production in some occasions. Multi-motor synchronous control is widely used in high-precision, high-speed transmission systems such as papermaking, printing and dyeing, textiles, and CNC machine tools. [0003] The multi-motor synchronous control of large-scale high-precision, high-speed transmission system is one of the most core issues. When multiple motors are running, affected by factors such as structural asymmetry, nonlinear characteristics, and load mismatch, even if the input is the same, the ru...
