说明：  单片机I/O口控制红外发射管，模拟格力空调遥控器的代码。典型应用：上位机发送一个通用的“开机，温度，模式……”命令，单片机自动发射出和遥控器一摸一样的波形，实现智能遥控器的功能。 (MCU I/O port control infrared emission control, analog Gree air conditioner remote control code. Typical applications: host computer to send a generic &quot boot, temperature, mode ... ...&quot command, microcontroller and the remote control automatically emit the same wave first touch, intelligent remote control functions.)

针对多电机同步控制中传统环形耦合 PID 控制存在抗扰动性不强 扰动下同步误差较大等问题， 提出了一种带前馈控制的滑模变结构多电机相邻耦合控制策略， 建立了3 台永磁同步电动机同步控制仿真模 型， 通过 Lyapunov 稳定性理论证明了滑模控制算法的稳定性， 并进行了交变负载 突变负载实验 仿真分析和 实验结果表明， 该控制策略相比传统环形耦合 PID 控制 相邻耦合 PID 控制具有更高的同步精度和更好的抗扰 动性能(Abstract: Aiming at the problem of poor anti-disturbance capability and big synchronization error under disturbance of traditional ring-couple PID control method in multi-axis synchronization control，a sliding mode variable structure with feed-forward control for relative coupling control strategy is proposed． Three Permanent Magnet Synchronous Motor ( PMSM) for synchronized control simulation modl is set up． The stability of the proposed control algorithm is proved according to Lyapunov stability theory． The control strategy is tested by alternating load，and mutant load experiment． Simulation analysis and experimental results show that the presented control strategy has higher synchronization accuracy and better anti-disturbance capability in camparison with the traditional ring-couple PID control and relative-couple PID control．)

该程序作用：将后缀为了；lrc的歌词文件，转换成 ulead 会声会影10.0 中的歌词导入文件（后缀为utf)。使用方法：先在文件中打开 .lrc 文件，然后开始转换，完毕可以查看结果，转换后的文件以 .utf 保存在同一目录下。(role in the procedure : To suffix; Lrc lyrics documents, converted into 10.0 ulead Huiqinghuiying the lyrics into paper (suffix for utf). Use : first opened in the document. Lrc file, and then started to change, can view complete results conversion of documents to. utf preserved in the same directory.)

电力系统电度表通讯协议，主要针对DL645协议标准(Power system meter communication protocol, mainly for DL645 protocol standards)
