Abstract

The invention discloses a linear servo system mechanical resonance control method which belongs to the field of mechanical equipment control. According to a control method in the prior art, on-line automatic adjustment of control parameters of a notch filter cannot be realized; a mechanical resonance suppression effect is poor; and the system requirements of high speed and high precision linear servo cannot be met. The invention provides a secant-based iterative learning algorithm to optimize the control parameters of the notch filter to solve the problem of resonance suppression of a linear servo system. The control method provided by the invention is simple, practical and highly precise.

Description

technical field [0001] The invention relates to a mechanical resonance control method of a linear servo system, which belongs to the 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 performance. The rich high-fre...
