| 中文摘要: |
| 针对三余度舵机系统对LVDT调理电路具有自监控功能的要求，提出了一种LVDT自监控信号的检测方法。在此基础上，运用时分复用技术，设计了采用一片LVDT信号调节芯片同时检测输出LVDT位移量信号和LVDT故障监控信号的调理电路。并对电路的线性度和故障检测能力进行了实验和分析。 |

| The authors present a novel detecting method of Liner Variable Differential Transformer Self-monitoring signal. Based on that, by a technology of time division multiplexing, the circuit using one chip of universal LVDT signal conditioner that can simultaneously process the output signal and the monitoring signal is designed. Experiments upon the linearity and fault detecting capacity of the circuit are performed and the results are analyzed. |
