这是一个比较典型的PID处理程序，在使用单片机作为控制cpu时，请稍作简化，具体的PID 参数必须由具体对象通过实验确定。由于单片机的处理速度和ram资源的限制，一般不采用浮点数运算，而将所有参数全部用整数，运算 到最后再除以一个2的N次方数据（相当于移位），作类似定点数运算，可大大提高运算速度，根据控制精度的不同要求，当精度要求很 高时，注意保留移位引起的“余数”，做好余数补偿。这个程序只是一般常用pid算法的基本架构，没有包含输入输出处理部分。-This is a typical PID process, as in the use of SCM control cpu, please slightly simplified, specific PID parameters to be specific targets identified by experiments. As SCM processing speed and ram resource constraints, generally do not use floating-point operations, and will use all the parameters of all integers, and the final calculations to divide one of the Nth 2 data (the equivalent displacement), will count for a similar operation, it will greatly increase the computing speed, control Accuracy of different requirements and high precision, displacement caused reservations to the attention of the "I", which I do several compensation. This procedure is commonly used algorithm pid the basic structure does not include input and output processing.

硬盘控制电路以及原程序Demo,知识是属于全人类的。能将自己的成果无条件与人共享是伟大和受人尊敬的，同时也是一件幸福的事。 由于我想得到幸福和受人尊敬，所以我也开放我的工作成果。（其实也不算什么工作成果，匆匆忙忙用了一晚写的，见笑了。 在此感谢邵春伟同志，我在研究ata协议的时候参考了他写的程序） -drive control circuit and the original procedure Demo, knowledge is the whole of mankind. The results can unconditionally with the people sharing is great and respected, but also a happy thing. I want happiness and well respected, so I open my work. (What is not a work haste spent a night writing, a laughing stock. This would SHAO Chun-wai comrades, I studied ATA agreement for the reference to the writing process)
