Embodiment Construction

[0062] In the example, such as figure 1 , 4. For the control accuracy of shaftless transmission, the speed control device of the multi-motor system of the IC material wire cutting machine tool includes:

[0063] Motion controller 13, choose the MP2300 motion controller of YASKAWA company, to realize the control of the line follow-up system;

[0064] The slave motors include the take-up motor and the pay-off motor 2, all of which adopt the ΣIII type servo driver and the ΣII type servo motor of YASKAWA company; the tension motor 4, the output torque applies tension to the steel wire; in order to record the tension, the pendulum 3 is balanced The position of the point, the speed sensor adopted by the two tension motors selects a 17-bit absolute value type photoelectric encoder 7;

[0065] The tension pendulum 3 arranged between the pay-off roller and the take-up roller of the cutting machine tool is used to adjust the speed synchronization between the two;

[0066] The absolute...

Abstract

The invention discloses a velocity synchronizing self-adapting inverse controlling means of IC material linear cutting machine multi-machine system for the problem existing in traditional PID controlling method. In multi-machine system linear velocity synchronous tracking controlling, the main electric machine system is identified in self-adaptive algorithm by using main electric machine as reference model, the main electric machine mathematical model obtained by identification self-adapting adjust the controller, and then the obtained self-adaptive controllers controls the linear speed of the driven electric machine to track the linear speed of main electric machine. The invention has advantages indicated by testing such as high control precision, stable operation and low tear string failure rate and so on.

Description

technical field [0001] The invention relates to a line speed tracking control technology of a winding system, in particular to a speed synchronous self-adaptive inverse control method of a multi-motor system of an IC material wire cutting machine tool. Background technique [0002] In traditional machinery, in order to achieve strict position synchronization and speed synchronization between the various motion units, mechanical shaft and gear transmission are usually used. Sometimes in order to change the speed ratio and phase relationship between the various transmission points, it is also necessary to install a gearbox and a differential. We call this method a shaft transmission method. Shaftless drives are also known as electronic shaft drives, independent drives, or mechanicalless drives. The characteristic is that each transmission point has its own independent driving motor, instead of driving multiple transmission points by one large motor. Therefore, only simple p...
