摘要
为了提高伺服作动系统的可靠性,设计了一种非相似余度作动系统,建立了非相似余度作动系统的数学模型,并分析了系统的性能。结果表明,非相似余度作动系统的动态性能比单通道工作时有所提高,在一个通道发生故障时,仍然能够正常工作。
In order to improve the reliability of servo systems, a dissimilar redundant servo actuator system was designed. The mathematical model of the system was estabhshed. The performances of the system was analyzed. The results prove that the dynamic performance of the dissimilar redundant actuator system is improved compared with the single channel system, and when one channel failed, the system could still work properly.
