Problems solved by technology

One is pure speed synchronization or position synchronization: this control method has exactly the same speed of the master and slave shafts, but it is difficult to ensure the balance of the torque of the master and slave shafts, especially when the mechanical consistency of the master and slave sides is not very good. Generally, the method can only be used in occasions where the mechanical coupling connection is relatively flexible.
The second is master-slave control (cancel the speed loop of the slave axis, and directly give the given value of the torque of the master axis to the slave axis): this control method can ensure the torque balance of the master and slave motors, but it is only applicable to pure mechanical coupling. Rigid occasion

Abstract

The present invention provides a method and device for multi-shaft coupling moment balance control based on position synchronization. The method comprises the following steps: controlling a main shaft and a slave shaft to perform synchronous operation through the given value of the same position; determining the given value of an additional position according to the moment deviation values of the main shaft and the slave shift; and regulating the moment equalization of the main shaft and the slave shaft based on the given value of the additional position. The method and device for multi-shaft coupling moment balance control based on position synchronization can ensure the position synchronization and the moment equalization of the main shaft and the slave shift based on position synchronization control, and are suitable for and include but not limited to the machinery coupling conditions of pure rigid connection, pure flexible connection and semi-rigid connection.

Description

Technical field [0001] The invention relates to the technical field of industrial control, in particular to a method and device for multi-axis coupling torque balance control based on position synchronization. Background technique [0002] Existing large-scale mechanical equipment usually requires multiple motors to be coupled and synchronously driven, including many mechanical systems that are coupled as semi-rigid connections. For the control of these mechanical systems, not only the speed of the master and slave shafts must be basically the same during operation, but also the torque balance of the master and slave shafts is required. However, the traditional control method cannot combine the above two points very well, so it is not suitable for the control of this semi-rigid coupling mechanical system. In addition, if there is a certain mechanical transmission gap between the coupled master and slave shafts, it is difficult to avoid torque oscillation. [0003] The more common...
