【摘要】 针对传统工程机械差速系统存在防滑功能不强的缺陷，提出以Intel8751单片机为控制芯片，以最佳滑移率S为控制目标，采用模糊逻辑控制为控制算法的自动防滑差速系统。系统开发包括三个方面的内容，一是系统硬件电路的设计，包括系统扩展、人机通道及前后通道设计；二是系统软件设计，包括利用MATLAB的FUZZY LOGIC模块进行模糊控制算法设计和主程序设计，还包括硬件接口程序设计；三是仿真系统设计及在MATLAB/SIMULINK模块下进行仿真的结果陈述。结果表明：基于模糊控制的自动防滑差速系统防滑性能好，自动化程度高，可实施性好。更多还原

【Abstract】 Aimed at the flaw of weak anti-slide function in traditional engineering machine, the thesis puts forward a new auto-anti-slide differential gear system controlled by Intel 8751 microcontroller, which adopts the fuzzy logic as its control algorism and the best slide ration(s) as system’s control target. The system exploit concludes three contents. First is the circuit design of system’s hardware, its main contents comprise the design of system exploration, people-machine passage and forward\rear passage .The second one is the software plan, include the fuzzy logic algorism design by means of Matlab/Fuzzy logic module and system main program design. The third part is the design of system simulation throughout Matlab/Simulink module and the statements of system simulation result. The result of the simulation indicates that Auto-anti slide differential gear system based on fuzzy logic control has a perfect anti-slide quality, its antomaticity and practicality are well-更多还原
