| 摘要: |
| 为了提高双余度机电作动器(EMA)伺服系统的可靠性和容错能力,分析了EMA系统中永磁无刷直流电机用线性可变差动变压器(LVDT)和旋转可变差动变压器(RVDT)及其辅助电路的故障在线自修复技术,提出了一种基于数据融合滤波算法的故障自修复控制策略。该方法可快速定位故障点,实现EMA伺服系统的故障检测与隔离(FDI),并对故障数据进行重组。该方法可有效提高EMA的可靠性、寿命和可维护性,满足EMA伺服系统的发展要求,推动其故障预测与健康管理的理论研究及技术应用进程。 |

| Abstract: |
| To enhance the reliability and fault tolerance of the dual-redundant electro-mechanical actuator of a servo system, we analyze the online fault self-repairing techniques of the linear variable differential transformer and rotational variable differential transformer which are used in the permanent magnet brushless DC motor of an electro-mechanical actuator (EMA). We propose what we believe to be its novel fault self-repairing strategy based on the data fusion filtering algorithm. The strategy can accurately and rapidly determine the fault location, realize the fault detection and isolation of the servo system and recombine the data of faulted sensor. It can effectively enhance the reliability, life and maintainability of the EMA, satisfy the requirements of its servo system and quicken the research progress in fault forecast and health management. |
