Servo control device and method for disc gap in disc powder grinding system

A control method for a disc gap servo control device for a disc powder grinding system, the method comprising the following steps:

• step 1, inputting a control information to an industrial computer through a touch screen, wherein the control information comprises a target rotating disc rotating speed and a target disc gap;
• step 2, transmitting a position information to the industrial computer through a position sensor, so that the industrial computer obtains a current disc gap accordingly and displays the disc gap on the touch screen;
• step 3, using the industrial computer to generate a control command according to a difference value between the current disc gap and the target disc gap and control a disc gap servo control device to adjust a disc spacing, which specifically comprises the following steps that:
• step 3.1, the industrial computer generates the control command according to the difference value between the current disc gap and the target disc gap, and controls an AC servo motor to rotate accordingly;
• and
• step 3.2, the AC servo motor is decelerated by a decelerator, drives a mechanical linkage, and further drives a rotating shaft and a rotating disc to move horizontally for a certain distance, so as to realize precise control of the disc spacing;
• step 4, repeating the steps 2-3 until the current disc gap reaches the target disc gap, then going to the next step;
• and
• step 5, controlling a rotating speed of a driving motor by the industrial computer through a frequency converter according to a target rotating disc rotating speed, and further controlling the rotating disc rotating speed, so that an actual rotating disc rotating speed can reach the target rotating disc rotating speed.
