PURPOSE:To utilize for operation and safety of a facility by adding a term of friction proportional to the input and output side speeds of an intermediate shaft to an equation of a monitor, thereby improving the operating conditions. CONSTITUTION:When a voltage Va is applied to the armature of a drive motor 10, an armature current Ia flows, a current If is supplied to a field, a torque tauM is generated, and the motor is rotated at a speed omega1. A roll 12 has an inertia moment J2, is driven at a speed omega2 by the motor 10 through an intermediate shaft 14. A disturbance torque tauL is applied to the roll 12. When the roll 12 is driven, the shaft 14 is twisted by an angle theta. When a load torque applied to a roll drive system is presumed, a term of a friction proportional to the input and output side speeds of an intermediate shaft is added to the equation which exhibits the relationship between the load torque and the acceleration of the roll, the twisting angle of the intermediate shaft to eliminate the difference in the actual behavior and the presumed result. |
