Example Embodiment
[0027] Embodiment 1
[0028] First, the structure of the door apparatus of Embodiment 1 of this invention is demonstrated. figure 1 It is an overall schematic diagram showing the structure of the door apparatus according to Embodiment 1 of the present invention. figure 1 A door apparatus used as a door of an elevator apparatus, for example, is shown.
[0029] in figure 1 Among them, the door device 1 has: door panels 1A, 1B, which open and close the entrance and exit of the elevator car; a hanger 2, which is installed at the upper end of the door panels 1A, 1B; and a beam 3, which is arranged with the long sides along the horizontal direction At the upper edge of the entrance and exit; and the guide rail 4, which is arranged on the beam 3 with its long side along the horizontal direction. The hanger 2 is provided with a plurality of hanging wheels 5, the hanging wheels 5 are placed on the guide rails 4, and the hanging wheels 5 move along the guide rails 4 to guide the horizontal m...

[0097] Embodiment 2
[0098] Image 6 It is a control block diagram showing the door control apparatus of Embodiment 2 of this invention. in Image 6 , Marked with figure 2 The parts with the same reference numerals represent the same or corresponding structures, and the description thereof is omitted. Image 6 The door control device is configured like the door control device of the first embodiment. The belt stiffness is estimated during the pressing operation, the frequency of the natural vibration of the door is calculated, and the frequency of the natural vibration is removed from the detected value of the movement speed of the door panel through filtering. Ingredients, thereby achieving smooth door opening and closing. The difference from Embodiment 1 of the present invention is that the belt stiffness is estimated with higher accuracy using the initial tension value of the belt. Hereinafter, the differences from the first embodiment will be described, and the description...

[0116] Embodiment 3
[0117] Figure 7 It is a control block diagram showing a door control device according to Embodiment 3 of the present invention. in Figure 7 , Marked with figure 2 The parts with the same reference numerals represent the same or corresponding structures, and the description thereof is omitted. Figure 7 The door control device of is a different structure from the door control device of the first embodiment. At the beginning of the opening and closing operation, the stiffness is estimated and the frequency of the natural vibration of the door characteristic is calculated, and the inherent vibration is removed from the detection value of the motor rotation speed by filtering. The frequency component of the vibration enables smooth door opening and closing.
[0118] Such as Figure 7 As shown, the door control device 12 according to the third embodiment of the present invention is configured to include a current command limiting unit 26 to which an operation co...
