【Abstract】 Aero-engines are developing in the miniaturization, totalization, high performance, and high dependability direction. Distributed control will become the important and promising direction of aero-engine control.The structure, functions, advantages of aero-engine distributed control systems were emphatically expatiated in this thesis. Key technology of the distributed control systems for aero-engines was pointed out. Design plan of the smart devices(including smart sensors and smart actuators) based on DSP and CAN buses was proposed. The anti-interference technology of the smart devices was discussed.Hardware circuits, encapsulation boxes and software of the smart devices were designed. The smart temperature sensor, smart pressure sensor, smart speed sensor, and smart positioning actuator were developed. The smart devices have small space and powerful functions, and can be organized in the network conveniently. The measurements and control experiments of the smart devices have been carried out, and the smart positioning actuator has been tested on the physical experiment bench. All experiments have showed good results.The physical model of aero-engine distributed control systems under the laboratory environment has been set up. The communication protocol based on CAN buses was proposed and has been tested on the physical model.更多还原
