摘　　要：针对飞行模拟器开发了一套油门台控制系统,以AT90CAN128为主控芯片,采用该芯片的内嵌CAN通信收发功能,设计了飞行模拟器油门台控制系统方案。采用电磁离合器切换工作模式,从而满足油门台在随动、手动工作状态下不同控制要求。系统通过高精度电位器实时反馈双油门杆的位置信息,并将反馈信息传给上位计算机。最后进行整机模拟系统联调试验,验证本系统方案可行性,试验结果表明所测试数据结果稳定,微调的分辨率小于0.5°,位置信号的偏差小于1%,响应时间小于0.1s。Using AT90CAN128 as the master chip, a throttle control system is developed for flight simulator. The chip embedded CAN communications transceiver functions are adopted for designing throttle control system of flight simulator program. This study uses electromagnetic clutch switch operating modes to meet the different control requirements of the throttle system in the servo operation mode and manual operation mode. With high-precision potentiometers, the system will feedback real-time information for the dual throttle lever position and put the information to the host computer. Finally, we test the feasibility of the system plan by debugging with the whole simulation system. The experimental results show that the test data results are stable; Fine-tuning resolution is less than 0.5°. The deviation of the position signal is less than 1%, and the response time is less than 0.1s.
