说明：  RTD2313E RTD2550 RTD2556 RTD2556T RTD2556QR VGA+HDMI+DP转EDP显示器方案设计(Rtd2313e rtd2550 rtd2556 rtd2556t rtd2556qr VGA + HDMI + DP to EDP display scheme design)

对delta sigma进行设计，实现delta sigma ADC的设计(this is use for delta sigma adc ,and design and achieve adc)

1.采用微分先行PID控制实现对液位的控制。 2.采用增量式PI控制实现流量的快速跟踪，且波动范围较小。 3.采用经验方法分别对上述两个PID控制器参数进行整定。 (1. Using differential PID control to achieve the first level of control. 2. Using PI control to achieve incremental flow of fast-track, and the fluctuation small. 3. By the empirical methods are two of the PID controller parameters tuning.)
