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.
