摘要：

为了提升高速开关阀（HSV）的动态性能，降低温升与能耗，提出基于电流反馈的高速开关阀3电压控制策略.回路中的电流能够反映高速开关阀的工作状态，通过外部的数字信号及回路中的电流反馈信号，实现3电压之间的自动切换，确保线圈中的电流始终处于能够维持高速开关阀快速启闭的最优化状态.通过理论分析验证了基于电流反馈的3电压控制策略，能够有效地提升高速开关阀的动态特性并降低温升和能耗.运用Ansoft和AMESim搭建高速开关阀的联合仿真模型，仿真结果验证了理论分析的正确性，且与样本数据保持一致.结果表明，基于电流反馈的3电压控制策略将高速开关阀的开启时间减少了35.3%，关闭时间减少了25.0%，最大可控频率提高了146.7%，可控占空比范围扩大了54.0%，平均功率降低了70.4%.
Abstract:

A three power sources excitation control algorithm of high speed on/off valve (HSV) based on current feedback (3PSCF) was proposed in order to improve the dynamic performance of HSV and reduce the temperature rise and energy consumption. The adaptive switching of three voltage sources was realized by external digital signal and current feedback signal in the loop which can estimate the operational state of the HSV. The current in the coil is always in the optimal state to keep a fast switching of HSV benefiting from the adaptive switching of three power sources. The theoretical analysis shows that the 3PSCF can effectively improve the dynamic characteristics of the HSV and reduce the temperature rise and energy consumption. A co-simulation model of HSV was established by Ansoft and AMESim. The simulation results confirmed the correctness of theoretic analysis and accorded with the catalog data. The opening time was shortened by 35.3%, and the closing time was shortened by 25.0%. The maximum controllable frequency was extended by 146.7%, and the controllable working duty ratio was extended by 54.0%. The average energy consumption was reduced by 70.4%.
