摘要/Abstract

摘要： 高速开关阀是数字液压系统的核心控制元件，具有响应快、抗污染能力强、结构简单等优势。动态特性是高速开关阀的重要性能指标，直接决定了系统的响应速度与控制精度。因此，在多阀同步使用或配合使用的应用场合中，保证各高速开关阀动态特性一致性尤为重要。然而，即使通过提高加工精度、选择高性能材料、优化装配工艺等方法，也无法确保高速开关阀动态特性的完全一致。为解决该问题，绕过了通过提高加工水平来改善一致性的传统途径，创新性地通过控制算法实现高速开关阀动态特性差异补偿。首先建立高速开关阀动态特性数学模型，探究线圈初始电流与电磁力对启闭滞后时间与运动时间的影响规律，然后提出基于多电压复合驱动技术的动态特性差异补偿方法，即通过针对性地设置高速开关阀各运动阶段的驱动电压，对其启闭滞后时间与运动时间进行调整，进而消除各阀动态特性的差异。最后对3个同批次高速开关阀开展了动态特性差异补偿试验，通过测试动态特性与压差-流量特性差异的变化情况验证了补偿方法的有效性。结果表明：经补偿后，3个阀之间启闭滞后时间与运动时间最大差异由1.94 ms缩小至0.01 ms，最大差异率由29.79%缩小至1.67%；压差-流量特性最大差异率由9.73%缩小至3.03%。

Abstract: High speed on/off valve(HSV) is the core control component of digital hydraulic systems, offering advantages such as fast response, strong contamination resistance, and simple design. Dynamic characteristic is the key performance indicator of HSVs, directly determining the response speed and control accuracy of the systems. Therefore, in applications where multiple HSVs are used synchronously or cooperatively, ensuring consistency in dynamic characteristic of each HSV is particularly crucial. However, even with the improvement in machining precision, the use of high-performance materials, and the optimization of assembly process, discrepancies in dynamic characteristic within the same batch of HSVs still cannot be completely eliminated. To address this issue, the traditional approach of improving consistency through enhanced manufacturing precision is bypassed. Instead, it proposes an innovative method to compensate for differences in dynamic characteristic via optimizing control algorithm. Firstly, a dynamic characteristic mathematical model of HSV is developed. Based on this model, the effects of initial coil current and electromagnetic force on the dynamic characteristic are analyzed. Then, a multi-voltage compound driving algorithm is proposed to compensate for differences in dynamic characteristic of HSVs. The algorithm adjusts the driving voltage at each stage of the HSV's movement in a targeted manner, thereby modifying the switching delay time and moving time. By doing so, the differences in the dynamic characteristic among the HSVs are effectively eliminated. Finally, a dynamic characteristic difference compensation experiment is conducted on three HSVs of the same batch. The effectiveness of the compensation algorithm is validated by testing the variation of dynamic characteristic and pressure-flow characteristic. The results show that, after compensation, the maximum difference in switching delay time and moving time among the three HSVs is reduced from 1.94 ms to 0.01 ms. Additionally, the maximum difference rate in switching delay time and moving time is decreased from 29.79% to 1.67%. The maximum difference rate in pressure-flow characteristic is dropped from 9.73% to 3.03%.
