摘　　要：文中介绍了发动机模拟式电子调节器低压压气机导流叶片调节通道的原理和控制规律,在此基础上提出了基于DSP技术的数字化调节方案。利用PID控制算法实现了对低压压气机进口导流叶片角度随低压转子换算转速变化的稳定控制,运用模块化思路分别设计了数字式控制器的硬件系统和软件系统,并通过试验数据拟合曲线验证了系统控制规律的准确性和有效性,为发动机其余控制通道数字化设计提供了一种可行的思路。Analog electronic regulator of turbofan compressor guide vane adjust channel principle and the control law were analyzed in detail,on the basis,the digital control scheme based on DSP technology was proposed,using PID control algorithm,the low pressure compressor imported guide vane angle changing with low voltage conversion speed stability control was achieved,the idea of modularization design was applied to design the digital controller hardware system and software system,and the accura⁃cy and effectiveness of the system control law were verified by the fitting curve of test data,which provides a feasible idea for the digital design of the remaining control channels of the engine.
