摘　　要：高速开关阀作为数字液压系统的核心控制元件,具有结构紧凑、频响高、抗污染能力强等优点,广泛应用在航空航天、工程机械、军工设备等关键领域。高速开关阀的动态特性决定了数字液压系统的响应速度和控制精度。针对现有的高速开关阀,优化驱动控制方法是提升其动态特性最直接和最经济的方式。综合分析国内外关于高速开关阀驱动控制方法的研究现状与进展。为提高高速开关阀的综合性能,其控制策略趋于多电压化发展,且对各阶段电压的匹配提出更高的要求。虽然现有的多电压控制策略通过优化高速开关阀的启闭初始电流,可同时实现高动态响应和低功耗驱动,但是高动态响应加剧了阀体间的撞击,导致高速开关阀启闭噪声大、振动剧烈,大幅缩短使用寿命。随着微电子技术、计算机技术和传感技术的融合发展,高速开关阀多电压驱动控制策略将朝着更精细化、智能化的方向发展,以兼顾高速开关阀响应快、能耗低、温升小、寿命长等关键特性。High speed on/off valve(HSV),the core control component of digital hydraulic system(DHS),has the advantages of compact structure,high frequency response and strong anti-pollution ability,so that it is widely applied in aerospace,engineering machinery,military equipment,and other important fields.The dynamic performance of HSV determines the response speed and control accuracy of DHS.For the existing HSV,optimizing the control method is the most effective and economical way to improve its dynamic performance.The research status and progress of HSV control algorithm are comprehensively analyzed.In order to improve the operation performance of HSV,its control strategy tends to multi-voltage algorithm,and higher requirements for voltage matching at each stage is put forward.Although the existing multi-voltage control algorithm can achieve both fast dynamic response and low energy driving by optimizing the switching initial current of HSV.However,the fast dynamic response intensifies the impact between the valve bodies,resulting in big noise and severe vibration of HSV,and significantly shortens its service life.With the integration of microelectronics,computers and sensing technologies,the multi-voltage control algorithm of HSV will develop towards a more refined and intelligent direction,and balance the key characteristics of fast response,low power losses,small temperature rising and long service life.
