Abstract

The invention provides a multi-hydraulic-cylinder coupling synchronous control system which comprises a plurality of hydraulic position servo links. Each hydraulic position servo link is used for controlling the action of a heaving hydraulic cylinder; and every two hydraulic position servo links are coupled, so that synchronous control over every two hydraulic position servo links is achieved. According to the multi-hydraulic-cylinder coupling synchronous control system, the multiple hydraulic position servo links are arranged and coupled in pairs, synchronous control over the two heaving hydraulic cylinders is guaranteed, phase lag is overcome, the stability of the hydraulic control system is improved, and the synchronous control precision of the multiple hydraulic cylinders is guaranteed.

Description

technical field [0001] The invention relates to the technical field of hydraulic synchronous control, in particular to a multi-hydraulic cylinder coupling synchronous control system and a multi-hydraulic cylinder cross-coupling synchronous control method. Background technique [0002] Compared with other forms of synchronous control systems such as motor synchronous control systems, the hydraulic synchronous control system has the advantages of convenient operation, easy control, simple structure and is very suitable for high-power applications. Therefore, in more and more metal processing equipment, metallurgical machinery, engineering machinery and driving devices, in order to increase the driving force, dual hydraulic cylinders or even multiple hydraulic cylinders are usually used to work together. urgent need for technology. [0003] Hydraulic synchronous control has been widely concerned by the industry, but the high-precision synchronous control has not been really so...
