Technical Field

The invention relates to the technical field of motor control, in particular to a self-adaptive attenuation control method.

Background

With the electrification of the present century, the world is driven by different electric machines to run at high speed. The energy conversion element is widely applied to life as a conversion element between electric energy and mechanical energy, and the trace of the energy conversion element can be seen everywhere. Small electronic equipment products and large industrial equipment.

However, the electrical and mechanical parameters of the motors produced by different manufacturers are different, and meanwhile, the parameters and the running speeds of the motors adopted by the whole machine factory are different, so that the problems of unstable running, audible noise, jitter and the like can occur if the debugging is not reasonable. By a suitable adaptation of the respective damping mode of operation, the influence thereof can be minimized.

Different attenuation modes need to adapt to different motors and different control moments, corresponding electrical and mechanical parameters of the motors need to be acquired according to the selected motors, and workers select the optimal mode to control the motors by combining various attenuation modes, so that the production cost and the consumed time are greatly increased.

Disclosure of Invention

In order to solve the problem that the production cost and the time consumption are greatly increased when the motor is controlled by selecting the optimal mode in the prior art, the invention provides the self-adaptive attenuation control method which can greatly reduce the production cost and time and ensure the stable and quiet running of the driving motor.

The technical scheme is as follows: the self-adaptive attenuation control method is characterized by comprising a motor and a detection control module, wherein the detection control module detects and arranges related motor data, selects a proper attenuation mode and drives the motor to run stably and quietly.

It is further characterized in that the motor starts to operate, and the motor is driven in a slow decay manner in a time period less than the minimum current determined by the detection part; driving the motor in a hybrid damping manner when the detected current is between the minimum determination current and the maximum determination current as the driving current increases; with the increase of the driving current, when the detected current is larger than the maximum judging current, the motor is driven in a fast attenuation mode;

in the current reduction stage, before the detected current is greater than the maximum judgment current, the motor is driven in a fast attenuation mode; then reducing, when the detected current is between the minimum judging current and the maximum judging current, the self-adaptive control part drives the motor according to a mixed attenuation mode; and reducing again, and driving the motor according to a slow attenuation mode after the detected current is less than the minimum judgment current.

After the invention is adopted, the motor part is an actuating mechanism, the detection control module is used for detecting relevant motor data, sorting feedback information of the detection part and selecting a proper attenuation mode, thereby driving the motor to operate stably and quietly.

Detailed Description

Referring to fig. 3 and 4, the adaptive attenuation control method is characterized by comprising a motor and a detection control module, wherein the detection control module detects and arranges related motor data, selects a proper attenuation mode and drives the motor to run stably and quietly.

Specifically, the motor starts to work, and the motor is driven in a slow decay mode in a time period less than the minimum current determined by the detection part; driving the motor in a hybrid damping manner when the detected current is between the minimum determination current and the maximum determination current as the driving current increases; with the increase of the driving current, when the detected current is larger than the maximum judging current, the motor is driven in a fast attenuation mode;

in the current reduction stage, before the detected current is greater than the maximum judgment current, the motor is driven in a fast attenuation mode; then reducing, when the detected current is between the minimum judging current and the maximum judging current, the self-adaptive control part drives the motor according to a mixed attenuation mode; and reducing again, and driving the motor according to a slow attenuation mode after the detected current is less than the minimum judgment current.
