摘　　要：分布式控制是未来航空发动机控制系统的重要发展趋势.作为航空发动机分布式控制系统的主要组成部分,提出了一种基于CAN总线的智能执行机构的设计方案,并给出了具体的硬件电路和软件算法.DSP实现智能执行机构的程序控制和自诊断,CAN总线完成发动机中央处理器与DSP的数据交换,步进电机实现精确的自整角机传感器位置控制.实验结果表明,对比目前的发动机执行机构,提出的智能执行机构克服了相位移动明显、误差大、响应速度慢等缺点,取到了良好的控制效果,对提高系统的测量精度及保证航空发动机的控制品质具有重要意义.Distributed control is the important development of aero-engine control system in the future. As the main components of aero-engine distributed control system （ADCS）, the design of intelligent actuator based on CAN bus was proposed. Then detailed hardware circuit and software arithmetic were designed. DSP realizes program control and self-diagnosis of intelligent actuator. CAN bus carries out the data exchange of DSP and aero-engine CPU. Repeater motor accomplishes accurate displacement control of Automatic Adjust-angle Transformer. Comparing with actual actuator, simulation demonstrates the proposed intelligent actuator shows many other advantages, such as decreasing phase angle measuring error, eliminating random noise and improving response speed. As a result, it is very important in actuator control precision and aero-engine control performance.
