Elevator position controlling apparatus and method |
摘要 |
In a position controlling apparatus and method for an elevator which controls a position of an elevator in accordance with a velocity command profile consisting of an acceleration region, a uniform velocity region and a deceleration region, a position controlling apparatus and method according to the present invention controls generation of a synchronization position error in the deceleration region. The position controlling method for the elevator of the invention includes the steps of: determining a deceleration starting point of a deceleration profile region; previously storing a command position corresponding to the time elapsed after the deceleration starting point; dividing the command position into a plurality of position regions; differently establishing computing formulas of a velocity command by each position region; determining the position region to which the command position at a present time belongs; computing a second velocity command value in accordance with a time using the computing formula corresponding to the determined position region at the present time; and controlling a position of the elevator car in accordance with the second velocity command value after the deceleration starting point.
