Embodiment Construction
[0052] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0053] The main solution of the embodiment of the present invention is: during the positioning process of the mechanical equipment controlled by the AC servo system, the control terminal obtains the positioning position and real-time position of the load end with the sampling period; according to the positioning obtained with the sampling period The position and the real-time position determine the vibration frequency of the load end; when the AC servo system controls the mechanical equipment to perform positioning again, the servo drive is controlled to suppress the vibration of the load end at the vibration frequency.
[0054]Existing robot and numerical control technology have been widely used in all walks of life, and its drive and control mainly rely on the servo system to perform, so in the modern industrial auto...

The invention discloses a mechanical vibration suppression method. The mechanical vibration suppression method is applied to a mechanical vibration suppression system. The mechanical vibration suppression system includes a control terminal. The method includes: the control terminal acquires sample data collected at the end of the load; The collected sample data is processed to obtain the vibration frequency of the load end; when the AC servo system controls the mechanical equipment to perform positioning again, the servo driver is controlled to suppress the vibration of the load end at the vibration frequency. The invention also discloses a mechanical vibration suppression system and a computer-readable storage medium. The invention can reduce the vibration amplitude at the end of the mechanical load controlled by the AC servo system, and improve the product processing efficiency.
Description
technical field [0001] The invention relates to the field of servo control, in particular to a mechanical vibration suppression method, system and computer-readable storage medium. Background technique [0002] At present, robots and numerical control technology have been widely used in all walks of life, and their drive and control are mainly performed by servo systems. Therefore, in modern industrial automation systems, servo systems have become an indispensable key link. Servo systems are driven by The components are divided into stepping servo system, DC motor (referred to as DC motor) servo system, and AC motor (referred to as AC motor) servo system. Among them, the AC servo system is increasingly widely used in the field of modern automation, such as used in positioning control devices such as textiles, packaging, assembly, and laser processing. Especially for low-rigidity equipment such as industrial robots, residual vibration is prone to occur at the end of the load...
