Problems solved by technology

At present, most of the control methods for residual vibration suppression in servo systems are based on input shaper suppression methods. This method is difficult to control the parameters of pulse amplitude and time period, and has a large operating error, which cannot meet the control requirements of linear servo systems.

Abstract

The invention discloses a method for controlling mechanical residual vibration of a linear servo system, and belongs to the technical field of mechanical device control. Most of current control methods for restraining residual vibration of the servo system are restraining methods based on input shapers, the methods have the shortcomings that pulse amplitudes and time period parameters are difficultly controlled, running errors are large, and control requirements of the linear servo system cannot be met. The method includes the steps: firstly, connecting the linear servo system, and downloading parameters into a chip on a motion control card; secondly, enabling the servo system to close a motor after controller parameters are downloaded; thirdly, collecting sampling points; fourthly, iterating error signals used for optimizing; fifthly, issuing iterative learning correction driving force to the motion control card again, and repeatedly iterating iterative learning processes to restrain resonance. Input signals subtract output signals to serve as error signals. The method is simple, practical and high in accuracy.

Description

technical field [0001] The invention relates to a method for controlling mechanical residual vibration of a linear servo system, belonging to the technical field of mechanical equipment control. Background technique [0002] The linear servo system is widely used in the fields of high-speed and high-precision numerical control systems, semiconductor chip manufacturing, and precision instruments due to the use of direct-drive mechanical structures, no intermediate transmission links, and the advantages of relatively small load inertia and high dynamic response. In order to give full play to the high-speed and high-precision performance of the linear servo system, the high-speed and high-precision motion controller is designed to become one of the key technologies for the linear servo system to give full play to the high-speed and high-precision performance. [0003] Due to the high-frequency response characteristics of the linear servo system, it has good acceleration perform...
