Thenovel speed control is using an inverse contact model by a neural network, trained by measured valuesof speed and torque, in order to compensate the nonlinear torque generation of the motor. Since thereference values of the bending wave control are calculated from the desired torque value by the neu-ral network, first an open loop control of the drive ́s torque is feasible and second common speed con-trol  schemes,  well  performing  in  common  electrical  drives,  can  be  applied.
