摘    要：现代冶金工业中,多个液压缸同时作用于同一设备的应用越来越多,为了保证多缸的协同运动,除了要求液压执行元件的选型一致外,电气控制的同步控制算法起到了非常重要的作用。同步控制算法是通过软件方法消除多个液压缸之间运动的差异性,弥补由于液压执行元件、载荷分布、管路、变形等因素造成的设备运动位移的不一致。本文以一种连铸机翻转冷床设备为实例,介绍一种适用于多个液压缸配合的电气同步控制算法,对该算法的应用进行了详细说明,并对此方法的特点进行了评述。

Abstract: Applications that multiple cylinders are acted on one machine simultaneously get more and more in modern metallurgical industry.In order to ensure synchronous movement of multiple cylinders,the synchronous control algorithm in electric control will play very important role except for same selection of hydraulic elements.A software control algorithm was adopted to achieve elimination of movement difference of multiple cylinders,and remedy the inconsistence of equipment movement displacement caused by hydraulic elements,load distribution,pipeline,distortion and so on.Taking turning cooling bed in continuous casting machine as an example,an electric synchronous control algorithm which can be applied to cooperation of multiple cylinders is introduced.Application of the algorithm is described in detail,and its characteristics are discussed.
