Abstract

The invention discloses a dual linear motor driven synchronization tracking control device and method. The device comprises a linear motor drive part, a strain detection part and a drive control part. The linear motor drive part comprises two linear motor drive devices which are completely identical in structure. The two linear motor drive devices are fixed on an experiment table in parallel and respectively comprise a linear motor, a linear guide rail, a slide block and a base. The strain detection part comprises a thin steel plate, a rotating shaft and a strain gauge. The drive control part comprises a servo driver, a motion control card, an industrial control computer, a strain controller and an A / D conversion card. Static and dynamic measurement can be performed by using the strain gauge so as to have the advantages of high sampling frequency and fast response speed, and the synchronization situation between two platforms can be monitored in real time.

Description

technical field

[0001] The invention relates to the field of linear drive tracking control, in particular to a dual linear motor drive synchronous tracking control device and method. Background technique

[0002] With the development of science and technology, a new impetus has appeared in the development of modern manufacturing industry, which marks more complex production tasks and high-precision production requirements. People have higher and higher requirements for the quality and product performance of mechanical equipment. In some occasions, controlling one motor can no longer meet the work requirements. In the process of equipment control, it is often necessary to coordinate and synchronously control multiple motion units so that they have a constant rotational speed or linear velocity or displacement to meet their work requirements. Under the new manufacturing development situation, the synchronous control method of the mechanical system is continuously developed, t...
