Problems solved by technology

[0002] The traditional virtual master axis synchronous control method regards the output signal of the speed controller of the slave axis as the load resistance and feeds it back to the virtual master axis. When the speed controller is saturated and the load of the slave axis changes suddenly, the output signal of the speed controller is quite different from the actual load resistance. , which reduces the synchronous control performance

Abstract

The multi-mover linear motor synchronous control system provided by the present invention applies the virtual spindle synchronous control technology to the multi-mover linear motor, which improves the cooperative control performance of the multi-mover linear motor; adopts the linear expansion disturbance observer to observe the driven parts Concentrated disturbance, compared with the scheme in which the output value of the speed controller is used as the load resistance of the follower, improves the feedback accuracy of the load resistance of the follower, and reduces the influence of the mass change of the follower on the multi-mover synchronization system; A multi-controller topology and signal communication scheme based on the multi-mover motion controller and the winding drive controller is proposed. The winding drive controller collects the absolute position of the coupled mover, the number of the coupled mover and the load resistance of the coupled mover, and transmits them through the high-speed bus. To the multi-actor motion controller, the multi-actor motion controller runs the virtual master and slave position feedback control, and the primary winding drive controller runs the mover speed feedback control and winding current regulation. The logic is clear and easy to implement.

Description

technical field [0001] The invention relates to the field of motor control, in particular to a multi-mover linear motor synchronous control system. Background technique [0002] The traditional virtual master axis synchronous control method regards the output signal of the speed controller of the slave axis as the load resistance and feeds it back to the virtual master axis. When the speed controller is saturated and the load of the slave axis changes suddenly, the output signal of the speed controller is quite different from the actual load resistance. , thereby degrading the synchronous control performance. [0003] Therefore, there is an urgent need in the art to provide a system or method capable of improving the synchronous control of multi-mover linear motors. Contents of the invention [0004] The object of the present invention is to provide a synchronous control system for multi-mover linear motors, so as to improve the dynamic / static synchronous performance of m...
