This paper describes the development and implementation of closed-loop control for an oval stamp forming die using Matlab®’s Simulink® and the dSPACE® ControlDesk®. A traditional PID controller was used for the blank holder pressure and an advanced controller utilizing fuzzy logic combining a Linear Quadratic Gauss controller and a Bang-Bang controller. The draw beads were used to control local forces near the draw beads. The blank holder pressures were used to control both wrinkling and local forces during forces. It was demonstrated that a complex, advanced controller could be modeled using Matlab’s Simulink and implemented in dSPACE ControlDesk. The resulting control systems for blank holder pressures and draw beads were used to control simultaneously local punch forces and wrinkling during the forming operation resulting in a complex control strategy that could be used to improve the robustness of stamp forming dies.
