YANG Quan-ting1, PANG Jing2, WANG Lei-tao1, et al. Aero-engine intelligent position actuator based on DSP and CAN bus[J]. 2012, 31(2): 109-111. DOI: 10.13873/j.1000-97872012.02.016.
As the main components of aero-engine distributed control system(ADCS)
a design scheme of intelligent position actuator based on CAN bus and DSP is proposed.The detail hardware circuit and software algorithm are given.DSP realizes closed loop control and self-diagnosis of intelligent actuator.CAN bus carries out the data exchange of DSP and aero-engine CPU.Experimental result demonstrates that the proposed intelligent position actuator has good performance.As a result
it is very important in actuator control precision and the research of aero-engine distributed control.
