Sliding Mode Force Control during Drawing Processes in Presses
نویسندگان
چکیده
Nowadays high-tonnage drawing presses need a controlled cushion so that the force is controlled during the drawing process. Although with a classic force control algorithm, consisting of a non-linear feedforward loop and a closed loop PID control, the results are normally quite good, there are times when tuning up is difficult and performance diminishes significantly at high rates. A new force control has therefore been developed applying sliding mode techniques, which is more robust than the previous control, especially in problem cases. Copyright © 2005 IFAC
