【四轴飞行器的位移控制】控制四轴飞行器的姿态和位置设计内环和外环PID控制回路（Simulink仿真实现）
11-30
【四轴飞行器的位移控制】控制四轴飞行器的姿态和位置设计内环和外环PID控制回路（Simulink仿真实现）内容概要：本文围绕四轴飞行器的位移控制展开，重点介绍如何通过设计内环和外环PID控制回路来实现对其姿态和位置的精确控制。外环负责根据期望位移生成姿态指令，内环则依据这些指令调节飞行器的实际姿态，从而实现稳定的位置跟踪。整个控制系统在Simulink环境中进行建模与仿真，便于验证控制策略的有效性与鲁棒性。文中详细阐述了四轴飞行器的动力学模型、控制结构设计原理以及PID参数整定方法，帮助读者深入理解飞行器控制的核心机制。; 适合人群：具备自动控制理论基础和Simulink仿真经验的高校学生、科研人员及从事无人机控制开发的工程师。; 使用场景及目标：①用于教学实践中帮助学生掌握多变量控制系统的设计方法；②为无人机姿态与位置控制系统的开发提供可复现的仿真框架；③支持进一步研究高级控制算法（如串级控制、自适应控制）在飞行器中的应用。; 阅读建议：建议读者结合Simulink模型同步操作，动手调试PID参数以观察系统响应变化，加深对内外环协同控制机制的理解，并可在此基础上拓展为非线性或智能控制策略的研究。
【嵌入式开发】Rust与C++互操作技术指南：基于FFI与bindgen的混合编程及渐进式迁移方案设计
11-30
内容概要：本文是一份关于在嵌入式环境中实现Rust与C++互操作的工程实践指南，系统介绍了如何将Rust逐步集成到现有的C/C++驱动框架中。内容涵盖互操作机制（如FFI、extern "C"、bindgen工具）、构建系统集成（Cargo与Make/CMake等）、内存与所有权管理、中断处理、调试测试流程及性能优化，并提供完整的实战案例——用Rust实现I2C传感器驱动并集成到C项目中。文章强调安全性、兼容性和渐进式迁移策略，附有大量可运行代码和常见问题解决方案。; 适合人群：具备一定嵌入式开发经验，熟悉C/C++，并希望引入Rust提升代码安全性的中高级工程师或技术团队；适合正在考虑语言迁移或模块重构的开发者； 使用场景及目标：①在现有C/C++项目中安全嵌入Rust模块，降低内存安全隐患；②实现高效跨语言调用，优化关键组件的可靠性与维护性；③通过bindgen自动化绑定、联合构建与调试，完成实际驱动开发与性能验证； 阅读建议：建议结合示例代码动手实践，重点关注FFI边界设计、内存安全规则和构建脚本配置，在真实嵌入式平台上进行调试与测试以掌握全流程。
