By predicting the noise in the loop the delay of noise signal in digital feedback loop is compensated effectively, thus the control capability of the system on disturbance is enhanced.

通过在回路中对噪声进行预测，有效地补偿了数字反馈回路造成的噪声信号的延迟，从而改善了系统的扰动控制性能。

Every schoolkid since the late 1950s probably remembers a self-study reader program just like this, from SRA. All that's really different in the digital age is the feedback loop.
