<P>PROBLEM TO BE SOLVED: To construct a damping control system robust with respect to a change in a vibrational eigenvalue and phase shifting depending on the position of a car and to achieve riding comfort having high stability, in a method for actively controlling a hoisting machine in order to absorb vertical vibration of the car. <P>SOLUTION: This elevator control device 11 detects the vibrational component of the car 1 using an acceleration detector 15 arranged in the car 1, generates a torque signal for suppressing the vibrational component, and feeds back it to a torque control system of the hoisting machine 5. In addition, the device 11 generates a speed signal for suppressing the vibrational component, and feeds back the speed signal to a speed control system of the hoisting machine. Thereby, it is possible to construct the damping control system robust with respect to the change in the vibrational eigenvalue and phase shifting depending on the position of the car and achieve the riding comfort having high stability. <P>COPYRIGHT: (C)2010,JPO&INPIT |
