Abstract (en)

[origin: EP3683181A1] An elevator door control device that provides both a speed following performance and a vibration suppression performance at the same time and ensures safety, and an elevator door drive system using the same are provided. The elevator door control device outputs a control command to drive a door mechanism disposed on a car (103) corresponding to a target command for a door operation state, and includes a controller (108) and an optimal controller (113). The controller (108) generates the control command corresponding to a control input. The optimal controller (113) has an evaluation index to evaluate the door operation state and the control input together, computes the control input to optimize the evaluation index, and outputs the computed control input to the controller.
