无人机全电刹车系统设计

为了提高无人机现有刹车系统的刹车性能和刹车效率,针对无人机全电刹车系统进行设计。与传统的液压刹车系统进行对比,简要分析了全电刹车系统的刹车原理和结构特点;特别针对全电刹车系统的关键技术即电作动机构进行深入的分析和研究,给出了相应的设计计算方法。对刹车控制盒设计采用了先进的基于最佳滑移率的模糊控制方式,并利用仿真软件MATLAB中的SIMULINK工具建立了整个系统的控制模型,仿真结果表明此控制律的设计还是比较成功的,刹车过程平稳,刹车效率较高。

Design on Electrical Brake System of UAV

In order to improve the performance and efficiency of the brake system of UAV,an electric brake system is designed.An analysis of synopsis is given for the operating principle and structure features of UAV,as compared with the traditional hydraulic brake system.The electric actuator which is the key technique of the system is specially analysed and studied in detail,and the design and calculating method is presented.A new control method is introduced in designing the brake-control box,which is an advanced fuzzy control law based on controlling wheel slid-ration.The whole control model is built with the tool of SIMULINK in the software of MATLAB,and the result of simulation indicates that the design of the control law is quite successful with a smooth brake and a higher efficiency.
