PID，C51实现

这是从网上找来的一个比较典型的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。-It is found from the Internet a more typical PID process, as a control in the use of single-chip cpu, please make some simplification, the specific parameters of the PID must be determined through experiments at specific audiences.
