DAMPING INJECTION CONTROL OF WINDING SYSTEMS BASED ON PORT CONTROLLED HAMILTONIAN SYSTEMS

In web and metal sheet processing systems and winders, flexibility of the web is a source of vibrations and resonance amongst motor drives. Port-Controlled Hamiltonian with Dissipation (PCHD) modelling is considered to develop stabilization strategies with a physical interpretation and motivation of the control action. A web transport system is modelled as a PCHD system and the control action is defined to obtain asymptotically stable operating points for the controlled system by a passivity argument. The controller negative output feedback gain matrix is interpreted as the realization of virtual dampers added to the system.
