摘　　要：使用滞环控制方法实现快速电磁阀两端电压的脉宽调制,精确控制流过快速电磁阀的强激电流和维持电流的幅值,使用变频变占空比的方法控制流过快速电磁阀电流脉冲的占空比,具备输入过压、输入欠压和输出短路保护功能,设计了一款基于滞环控制的快速电磁阀控制仪。该快速电磁阀控制仪已经在航空发动机快速电磁阀及其主燃油控制附件的维修过程批量使用,杜绝了因控制器输入信号不稳定导致的航空发动机主燃油系统故障,且抗干扰能力强,能够预防维修过程人为差错,起到了提高航空快速电磁阀维修质量的作用。The amplitudes of strong pull-in current and hold-on current passing through the high speed solenoid valve were regulated accurately by using hysteresis control to realize pulse width modulation of the voltage of fast solenoid valve,the duty cycle of the current pulse passing through the high speed solenoid valve was controlled by variable frequency control with variable duty cycle,and the protection functions of input overvoltage,input undervoltage and output short circuit were designed.A high speed solenoid valve control instrument was designed based on hysteresis control method.By using the proposed high speed solenoid valve control instrument during the maintenance of aeroengine high speed solenoid valve and main fuel control accessories,the fault of main fuel system of aeroengine caused by unstable input signal of controller was eliminated.Benefited from strong anti-interference ability of the proposed instrument,instrument damage caused by misoperation in the maintenance process was prevent,maintenance quality of high speed solenoid valve has been improved.
