Abstract :
In this paper a 2-inertia control system is proposed on an original point of view of the minimum-phase state. The anti-resonant and resonant characteristics of 2-inertia system resolved into the tandem model of extended minimum-phase and extended all-pass functions. The feedback control on the extended minimum-phase state is able to compensate the perturbation of the torsional vibrations and the disturbance torque. Numerical example shown in the simulation of the motor and load velocity control improved the robust stability and responses.
