涡轴发动机动力涡轮转速控制回路方案研究

Speed Control Loop Schemes for Power Turbines of Turboshaft Engine

比较分析了航空涡轴发动机动力涡轮转速回路的2种控制方案(单回路控制方案和串级控制方案)。针对单回路控制方案控制性能差、串级控制方案参数整定繁琐的缺点,提出了一种新的串级控制方案。试验结果表明,新的串级控制方案性能优于原来的2种控制方案的。

Two speed control loop schemes for power turbines of turboshaft engine are analyzed by comparison. In view of the low control performance of single loop control and the complicated parameter calibration of the initial cascade control, a new cascade control scheme is proposed . Test results show that the new scheme is superior to the previous two.
