Embodiment Construction

[0024] The present invention proposes a master-slave synchronization control method with self-adjustment of the main shaft, which is used in a multi-cylinder synchronization system, where the shaft is a hydraulic cylinder. The present invention optimizes the traditional master-slave synchronization control and avoids the disadvantages of the slave shaft lagging behind the main shaft. The optimal tracking axis is selected in real time as the current master axis, and the master axis's synchronous adjustment of each slave axis ensures excellent synchronization performance without affecting the tracking performance of each axis. The invention has a simple control structure, is easy to debug, and has obvious engineering application value.

[0025] The specific implementation steps of the present invention are as follows:

[0026] a) According to the process requirements, plan the curve of each axis and generate the position command CmdPos(i), where i is the axis number of each axis;

[0...

Abstract

The invention discloses a multi-cylinder synchronous control method. According to the process requirements, all shafts are subjected to curve planning at first, the good tracking property of all the shafts is ensured through a position tracking algorithm, according to the excellence of the tracking properties of all the shafts, an optimal main shaft is determined in real time, all auxiliary shaftsare subjected to synchronous compensation based on the optimal main shaft, and finally synchronous operation of all the shafts is achieved. By selecting the optimal main shaft in real time, a traditional fixed main shaft mode is replaced, meanwhile, through deviation between the main shaft and the auxiliary shafts, auxiliary shaft position instructions are corrected, and a controller side is alsosubjected to synchronous compensation. The defects that during main auxiliary synchronous control, due to the fact that a main shaft is selected improperly, the tracking property of auxiliary shaftsis reduced, the synchronous property is limited, and the auxiliary shafts lag behind the main shaft are overcome, and the method has the advantages of the simple structure and easy debugging and is obvious in engineering application value.

Description

Technical field [0001] The invention belongs to the technical field of forging manufacturing, relates to a synchronization system of a forging equipment, and is a multi-cylinder synchronization control method. Background technique [0002] In the field of forging manufacturing, with the improvement of the precision and complexity of molded parts, higher and higher requirements are put forward for the synchronization system in the forging equipment. For multi-cylinder synchronous pressing or multi-cylinder leveling systems, how to overcome each cylinder The difference in performance and the influence of eccentric load, improving control performance, ensuring product quality, and prolonging equipment life have always been the key difficulties in the research of synchronous control strategy in the forging industry. [0003] Four-corner leveling is a typical application of multi-cylinder synchronous control technology. It is widely used in forming equipment such as FRP products. It is ...
