Abstract

The embodiment of the invention provides an electro-hydraulic driving system control method and device, electronic equipment and a storage medium. The method comprises the steps that the estimated displacement ratio of a hydraulic transformer under a displacement following strategy is determined; a current control strategy is selected from a pressure feedback strategy and the displacement following strategy based on the estimated displacement ratio and a real-time pressure value of an energy accumulator; and the electro-hydraulic driving system is controlled by utilizing the current control strategy. According to the electro-hydraulic driving system control method and device, the electronic equipment and the storage medium in the embodiment, on the premise of ensuring the driving performance of an electro-hydraulic driving system, the energy recovery amount and the reuse rate of the recovered energy are improved.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to a control method, device, electronic equipment and storage medium of an electro-hydraulic drive system. Background technique [0002] In the process of energy-saving development of electro-hydraulic drive systems, the combination of accumulators and hydraulic transformers is usually used to recover and reuse the energy with recovery value. [0003] In the prior art, the displacement of the hydraulic transformer in the electro-hydraulic drive system is usually controlled, so as to realize energy recovery and reuse in each working cycle of the system. Since the control method for the displacement of the hydraulic transformer is usually fixed, the amount of recovered energy is small, and the reutilization rate of the recovered energy is low. Contents of the invention [0004] Embodiments of the present invention provide an electro-hydraulic drive system control method...
