Liquid Level Automatic Control System for Aluminum Rod Continuous Casting and Rolling
In this paper,high-temperature aluminum special laser liquid level meter with stepping motor and lever mechanism to achieve automatic control of liquid level.It is difficult to control the opening by taper plug because of the large down-flow orifice of the aluminum storage tank,the small change of the taper plug up or down,and the great change of the flow rate,so the conventional PID algorithm can not realize the effective control.In this paper,according to the characteristics of the stepping motor using variable parameter incremental PI control algorithm,through the incremental control algorithm to control the step motor forward(or reverse),the increment control algorithm has a direct effect on the lev-el control effect of the aluminum liquid gate.
