The research and application of the load - control system were studied in this article 本文主要论述了球磨机负荷控制系统数学模型的建立与应用。
According to the results of the analysis and the experiment , the mathematic model of the ball mill load - control apparatus was established and its sample was successfully designed 根据多次试验和分析结果,建立了球磨机负荷控制系统的数学模型,也完成了其样机的设计。
Because the traditional control method that was based on the temperature and pressure difference cannot achieve this aim , so in this project , the mathematic model of the load - control system was established mainly based on the ball mill ' s sound and its sample was designed 本文主要根据磨音来建立球磨机负荷控制系统的数学模型,并且进行了球磨机负荷控制仪样机的设计。
The ball mill load - control apparatus adopted the assembly language and the c51 language to program and its concerned software was designed , including the data collection , the wave - percolation , the short - time average over - zero ratio , the estimation of the power chart and the average - period chart 磨机负荷控制仪软件使用汇编和c51编程,本文进行了相关软件的设计,包括数据采集、滤波、短时平均过零率、功率谱估计和平均周期图等。
It was demonstrated that this sort of load - control apparatus has superior performance . we used a electric transmitter as the transducer to collect the sound signal , using the daq toolbox of the matlab to achieve the collection of the sound signal , and using the dsp toolbox of the matlab and the sound - launch technology to analyze the time - domain characteristic and the frequency - domain characteristic of the signal , chiefly analyze its short - time average amplitude , its short - time over - zero ratio and its estimate of the power chart and the average - period chart 实验中使用了驻极体话筒作为球磨机声音拾取传感器,利用matlab中的数据采集( daq )工具箱实现对磨音的采集,利用matlab信号分析( dsp )工具箱和声发射技术对磨音进行时域和频域分析,主要分析磨音的短时平均幅度和能量、短时平均过零率、功率谱估计和平均周期图。
