Development situation of turboprop engine in western countries was overviewed, and several key technologies related with the control system of turboprop engine were analyzed, including working parameters, features, performance, propeller model, design method of control system, fault diagnosis technology of different types of turboprop engines and so on. The adaptive fuel control logic and implementation method of the hydro-mechanical control system of Garret early YT76 single spool turboprop engine were mainly analyzed. In addition, the development process of Pratt&Whitney Canada three-spool turboprop engine from the first generation of supervisory digital electronic control with mechanical back up system of PW120 engine to the dual channel full authority digital eletronic control system of PW150 engine was selective analyzed. These efforts are intended to provide a clear idea for the technological development of domestic turboprop engine control system.%概述了国外涡桨发动机的发展状况，分析了涡桨发动机控制系统相关的若干关键技术，包括不同类别涡桨发动机的工作参数、特点、性能、螺旋桨模型、控制系统设计方法、故障诊断技术等。主要剖析了早期的Garret公司YT76单轴涡桨发动机液压机械控制系统的自适应燃油控制逻辑、实现方法，此外，对PW加拿大公司3轴涡桨发动机从第1代具有监控功能的数字电子控制系统及液压机械备份PW120发动机控制系统到具有双通道全权限数字电子控制功能的PW150发动机控制系统的发展历程进行了重点分析，旨在为国内涡桨发动机控制系统的技术发展提供1条清晰的思路。
