说明：  simulink系统仿真：10kV 母线短路容量为10MVA，通过额定电压10/0.4kV，额定容量为100kVA，短路阻抗为5％的变压器与负荷相连， 阻感负荷RL 容量为50kVA，功率因数0.9。电力电子装置产生的5 次和7 次谐波电流均为5A；为了抑制7 次谐波在400V 母线处接入电容与变压器构成7 次滤波器。(simulink System Simulation: 10kV busbar short-circuit capacity of 10MVA, through the rated voltage 10/0.4kV, the rated capacity of 100kVA, short-circuit impedance of 5 of the transformer and load connected to sense the load resistance RL capacity 50kVA, power factor of 0.9. Generated by power electronic devices 5 and 7 harmonic currents are 5A to suppress harmonics in the 400V bus 7 access to capacitors and transformers constitute at 7 filter.)

一个线性预测的matlab仿真程序，先用模型生成原始信号(平稳随机过程)，然后利用最小均方误差准则计算出预测系数，最后利用预测系数对原始信号进行预测(利用原始信号过去n个时刻的值预测当前时刻的值)。(This is a matlab program for linear prediction. First, we use all-pole model to generate a signal(stationary signal), then utilize the Minimum Mean-Square Error to compute the filter cofficient, at last we can use the filter cofficient to predict(use past n signal data to predict current signal data).)

锁频环又称为自动频率控制（AFC）环，其利用反馈回路对输入频率变化进行调整，最后达到对频率的跟踪，广泛应用于雷达，卫星导航等领域对多普勒频率的跟踪。(Locked loop, also known as automatic frequency control (AFC) loop, the use of feedback loop to adjust the input frequency changes, and finally achieve frequency tracking is widely used in radar, satellite navigation and other fields on the Doppler frequency tracking.)

说明：  灰色模型预测是在数据不呈现一定规律下可以采取的一种建模和预测方法，其预测数据与原始数据存在一定的规律相似性(Grey model prediction is a kind of modeling and prediction method that can be adopted when the data does not show certain rules. There is certain regularity similarity between the prediction data and the original data)
