说明：  pid参数与控制特性的相关性 为了更好的理解这个视频和PID参数的作用，特意根据多轴飞行器的原理和PID理论，编写了一个EXCEL图表，直观的来理解PID参数的作用。
(Correlation between PID parameters and control characteristics In order to better understand the video and the role of PID parameters, specially according to the principle of multi axis aircraft and PID theory, compiled an excel chart, intuitive to understand the role of PID parameters.)
