摘要

The purpose of this study ia 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 PICI8F 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 Matlah/Simulink.The result shows that the system can catch the input and output data accurately. Experiment on the precise !ow-speed rotary shows that the system is stable, reliable, accurate, and its real-time performance is good.%文中的研究目的是建立倾转旋翼飞机的模型,从而解决倾转旋翼飞机的控制问题.介绍了基于PIC18F单片机和微机械(MEMS)传感器的微小倾转旋翼机纵向通道辨识建模系统设计.其中系统设计采用了实验建模的方法,利用PIC单片机的CCP模块实时捕捉遥控输入信号,利用MEMS传感器实时采集飞行姿态信号,并在MATIAB/SIMULINK环境下进行了仿真.仿真结果表明系统能够准确采集输入和输出数据.通过精密低速转台测速实验,证明该系统工作稳定,精度可靠.实时性较好.
