摘要

摘要: 设计了一种新型的电气三余度直接驱动阀(DDV,Direct-Drive-Valve)驱动控制系统,介绍了系统结构,分析了三余度永磁无刷直流力矩电机、位置传感器以及交叉通道数据链(CCDL,Cross Channel Data Link)模块的方案设计,探讨了基于新型变结构PID算法的位置伺服控制策略和基于CCDL的余度管理策略.实验结果表明,系统具有良好的动静态性能以及冗余工作特性,其角度范围为-10° ~10°,定位精度不大于4′,三通道工作时频宽不小于20Hz,两通道工作时频宽不小于15Hz,可满足航空DDV式作动器的要求.

Abstract: The design and implementation of a triplex-redundancy control system for direct-drive-valve (DDV) were presented. The total structure of the system was built up. The schemes of triplex-redundancy brushless DC motor, transducer and cross channel data link (CCDL) were analyzed. Meanwhile, the strategies of servo control based on variable-structure PID and redundancy management based on CCDL were researched. Experiment results suggest that the proposed system possesses well steady and dynamic performance, and maintains good operation characteristics after first or second electrical failure. Main characteristics of the system are that the range of angle is from -10° to 10°, the precision is less than 4′, and the bandwidth is up to 20Hz for dual redundancy and 15Hz for single redundancy. The system satisfies the DDV actuator of airplane.
