Controller Design for the nonlinear Resin Transfer Molding-Process by Output Coupling

The Resin Transfer Moulding is a processing technique for fibre reinforced plastics and can be used to fabricate complex shapes. The governing equations to describe the dynamical behavior of the process are nonlinear partial differential equations defined on a complex domain. To avoid defects due to enclosed air in the moulding process a controller should be implemented. The basis for controller design is a reduced order descriptor model resulting from Proper Orthogonal Decomposition combined with a modified Galerkin approach. To achieve a harmonic behavior of the flow front a dynamic coupling output controller is implemented. Simulations with a complex geometry show the prospects of this approach.
