Power mechatronics / drives

Research focus and projects:

  • Investigation of active measures for damping vibrations in rolling mill drive systems

    • Modeling the behavior of rolling mill drive systems and the processes in the roll gap
    • Development of adaptive control concepts for active damping of self-excited vibrations (so-called "chatter") in rolling mill drive systems

  • Drive controllers with active vibration damping

    • Identification with genetic algorithms
    • PI state controller with self-adjustment

  • Mains-fed ASM with variable cage structure

    • Low-loss dynamic characteristic curve adjustment
    • Shaft torque-dependent control of slip
    • Semiconductor controller integrated in the rotor

  • Lifetime-optimized control of electric drives

    • Inverter with drive train adaptation
    • Cost-effective realization for SMEs
