Abstract:

At present,the strip extruding machine control system is mostly open loop,and the controlling effect is poor when it is disturbed.This paper presents a double loop feedback control method based on image processing.The applications for PC are written using the Canny filtering and mathematical morphology.The feedback control system is performed by PID method.Matlab simulation proves that this method has a good control effect.

Key words: morphology;Canny operator;PID;Matlab
