飞控系统是无人机的核心,无人机的外部架构对其性能的影响也很重要。为了提高无人机系统性能,给出一种无人机控制系统设计并进行了实验。文章在介绍变形飞行器和飞控系统功能要求的基础上,给出了基于芯片LPC2148的硬件设计,介绍了各个硬件部分的功能、软件架构和控制规律的选择与设计,详细介绍了实验的准备工作和实际飞行情况,给出了软件调试流程图,分析了调试结果。经过多次飞行试验,表明系统的设计是适合实验中的可变形飞行器的,并且合理可靠,能够完成预期的飞行任务,具有较好的实用性.
Flight control system is the core of the UAV, UAV’s external architecture of its performance is also very important. In order to improve the performance of UAS, a control system design of UAV and experiments are given. Based on the introduction of the functional requirements of the modified aircraft and flight control system, the article gives the hardware design based on the chip LPC2148, introduces the selection and design of the functions, software architecture and control laws of each hardware part, and introduces the preparation work of the experiment And the actual flight situation, gives the software debugging flow chart, analyzes the debugging result. After many flight tests, it shows that the design of the system is suitable for the experimental deformable aircraft, and it is reasonable and reliable to be able to accomplish the expected flight mission and has good practicability.
