Abstract:: The purpose of this study is to establish the model of tilt rotor aircraft, so as to find an approach to the control problem. In this paper, design of longitudinal channels identification modeling device of micro tilt rotor vehicles based on PIC18F is mainly introduced. In the model, the system design uses an experimental model, the device uses CCP modules of PIC MCU to capture the remote controlled input signal and uses the MEMS sensors to acquire fly attitude signal in real time, and the simulation is performed with Matlab/Simulink. The result shows that the system can catch the input and output data accurately. Experiment on the precise low-speed rotary shows that the system is stable, reliable, accurate, and its real-time performance is good
