并且为这套系统建立数学模型，以此模型用Matlab语言进行仿真研究。其结果表明，此功率因数自动控制系统在空载、欠载运行时节能效果显著。

Finally we establish a system model with which we simulate and analyze the control system through MATLAB . The simulation results demonstrate that it can save up energy about 30-50 % when there is no load or a little load .

注意：当系统欠载时，最大响应时间接近于停顿时间。

Notice that the maximum response times are close to the pause times when the system is underloaded .

该系统能有效地避免磨机发生胀肚和欠载现象的发生，稳定和提高磨机的各项工作指标，保证控制系统的合理性和经济性。

This scheme can effectively avoid the occurrence of over-load and under-load of the mill , maintain all work index of the mill , and ensure the control system to be reasonable and economical .

其主要原理是接收方反馈一个二进制位的过载或欠载信息，接收方根据此二进制信息，采用线性的加法增加乘法减少算法调节发送方的负载。

Its principium is that the receiver feedback a binary bit that indicates the information of overload or under load to the sender , and the sender adjusts the load with AIMD algorithm according to the binary information .
