网页音乐播放器(个人制作)
在网上看到很多网页音乐播放器，做得都很精致漂亮，却看不到它们的代码。我在大学毕业时做的毕业设计——在线音乐网站实现，搜集了很多网页音乐播放器的资料，加上现在的整理，自己做了一个网页音乐播放器。 相关的说明在压缩包的【readme】文件中，希望给予正在开发网页音乐播放器的人员一个参考。

单片机恒温箱温度控制系统的设计
198KB的《单片机恒温箱温度控制系统的设计 》那个传错了！不号意思！请下这个！1、利用单片机AT89C2051实现对温度的控制，实现保持恒温箱在最高温度为200℃。2、可预置恒温箱温度，烘干过程恒温控制，温度控制误差小于±2℃。3、预置时显示设定温度，恒温时显示实时温度，显示精确到0.1℃。4、温度超出预置温度±5℃时发出声音报警。5、对升、降温过程没有线性要求。6、温度检测部分采用DS18B20数字温度传感器，无需数模拟∕数字转换，可直接与单片机进行数字传输7、人机对话部分由键盘、显示和报警三部分组成，实现对温度的显示、报警。

基于非线性干扰观测器的直升机滑模反演控制
1、原论文及matlab仿真程序；2、提出一种基于非线性干扰观测器的滑模变结构控制方法。用一种非线性干扰观测器观测系统的不确定性和外界干扰，通过选择设计参数，可以使观测误差指数收敛。对引入非线性干扰观测器后的系统设计滑模变结构控制控制器，控制律的设计能够减小滑模抖震，保证闭环系统的稳定性，从而达到了对俯仰系统跟踪控制的目的。仿真结果表明，该方法能够较理想地观测干扰，减小控制器的输出，改善系统的控制性能。
