The dynamic behavior of the presdnted method was simulated by means of an advanced simulation tool:simulink tools based on MATLAB environment,which can optimize its parameters and rationalize its structure.Based on the gathered current data,an even current coefficient,the standard deviation and the current caninity curve can be given respectively.Since they are applied in AL-Electrolyzing,it is possible to distinguish the anode of which the current is not evenly distributed,and to take adjusting measures over a period of time to ensure that the current is evenly distributed;and thd dilapidation of the electrobath can be located in time.All these solutions are useful not only to improve the roasting quality,shorten the time interval,and raise the quality of the electrolysis in the aluminum electrolytic bath.
