摘　　要：LVDT(Liner Variable Differential Transformer)传感器是一种差动式变压器,用于将机械位移信号转换成电信号,具有灵敏度高、线性度好、分辨率高、寿命长及可靠性高等优点,在航空领域有着广泛的应用。由于LVDT传感器的输出信号为差分信号,传统的仪器仪表不能直接模拟LVDT传感器的信号,所以研制LVDT传感器仿真器替代真实的LVDT传感器,用于飞机机载系统的地面调试和试验。The LVDT（Liner Variable Differential Transformer） sensor is actually a kind of differential Transformer.It is used to transfer the mechanical displacement signal to the electrical signal.It has the feature of high sensitivity、 good linearity、 high resolution、 long life and high reliability,so it is widely used in the field of avionics.The LVDT sensor outputs the differential signal and it can＇t be simulated directly with traditional instruments,so the simulator of the LVDT sensor plays an important role in researching and testing the function of the flight control system instead of the real LVDT sensor.
