摘要：【中文】本发明公开了一种液压缸同步控制方法及用于控制多液压缸同步动作的系统，包括：根据已确定的基准液压缸以及基准液压缸对应的同步基准速度相对于每个液压缸的最大移动速率的实际速度比率，利用预设的输入输出映射网络模型，由实时获取到的指令输入信号得到针对每个液压缸并满足线性控制条件的实际驱动信号；向每个比例阀输出相应的实际驱动信号，以通过比例阀来控制对应液压缸的移动速度，从而补偿每个液压缸的实际移动速度差带来的不同步位移。本发明省去了复杂的PID调试环节，解决了闭环控制在特定情况下会造成液压缸不同步现象的缺陷，运算方法简单，尤其适用于较低性能的控制器，经济实用。 【EN】The invention discloses a synchronous control method of hydraulic cylinders and a system for controlling synchronous actions of multiple hydraulic cylinders, wherein the method comprises the following steps: according to the determined reference hydraulic cylinders and the actual speed ratio of the synchronous reference speed corresponding to the reference hydraulic cylinders relative to the maximum moving speed of each hydraulic cylinder, obtaining actual driving signals which are specific to each hydraulic cylinder and meet linear control conditions by using a preset input-output mapping network model through command input signals acquired in real time; and outputting corresponding actual driving signals to each proportional valve to control the moving speed of the corresponding hydraulic cylinder through the proportional valve, so that different displacement steps caused by the difference of the actual moving speed of each hydraulic cylinder are compensated. The method saves a complicated PID (proportion integration differentiation) debugging link, overcomes the defect that the closed-loop control can cause the asynchronous phenomenon of the hydraulic cylinder under a specific condition, has simple operation method, is particularly suitable for a controller with lower performance, and is economical and practical.
