AI Technical Summary

Problems solved by technology

Therefore, the method is complicated to operate and difficult to implement
In addition, the gap between the components of the servo actuator will change irregularly during the use of the system, and the error between the set fixed gap compensation value and the actual gap value will gradually increase until it becomes distorted. Therefore, in the actual application process The new position compensation value must be reset frequently in

Embodiment Construction

[0020] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0021] figure 1 A gap compensation method for a servo control system according to an embodiment of the present invention is shown, including the following steps:

[0022] S10, the magnitude of the servo driving force or the magnitude of the force of the servo actuator is detected, and the moving position of the servo actuator is detected. The servo control system in this implementation includes a pressure detection device, a position detection device and a servo controller, and the pressure detection device and the position detection device are all installed in the servo actuator element. The pressure detection device can use a pressure sensor, and the pressure sensor transmits the pressure signal of the detected servo driving force or the reaction force received by the servo actuator element to the servo controller in real time...

Abstract

The invention provides a gap compensation method for a servo control system, which comprises the following steps: detecting the magnitude of servo driving force or loaded force of a servo actuating mechanism and the displacement position of the servo actuating mechanism; and when the increasing speed of the servo driving force or the loaded force of the servo actuating mechanism reaches a predetermined value, setting the position of the servo actuating mechanism as an original point position of servo movement. When the servo driving force or the loaded force of the servo actuating mechanism is sharply increased, no gap exists between components of the servo actuating mechanism, and a servo controller sets the position of the servo actuating mechanism at the time as the original point position of servo movement to automatically perform gap compensation. In the gap compensation method, the gap between the components of the servo actuating mechanism does not need to be pre-measured, and the obtained gap compensation value is relatively accurate.

Description

technical field [0001] The present invention relates to a servo control system, in particular to a gap compensation method for a servo control system. Background technique [0002] In the servo control system, the gap between the components of the servo actuator has a great influence on the accuracy of the servo control, and even affects whether the servo control system can work effectively and normally. In order to improve the control accuracy of the servo control system and ensure the effective and normal operation of the servo control system, it is necessary to detect and compensate the gap of each component in the servo actuator. At present, the more commonly used gap compensation method is the fixed gap compensation value method, that is, the existing gap between the components of the servo actuator is measured first, and then a fixed gap compensation value is set in the servo controller, and the servo control system uses this. Servo control is performed based on the b...
