The research of feedback-feedforward iterative learning control in hydrodynamic deep drawing process
This paper firstly introduces the characteristics of hydrodynamic deep drawing(HDD)which is an important sheet metal forming technology,then points out the necessity of the chamber pressure control.Secondly considering the characteristics of the drawing action is repeated,iterative learning control(ILC)is the proper algorithm.Then introduces the concept of iterative learning control and feedback-feedforward iterative learning control to solve the delay and improve system robustness.Finally,the computer iterative learning control algorithm implementation process is given and the effectiveness of the algorithm is verified by simulation.
