Provided is a control device for an elevator exhibiting good follow-up performance wherein accurate inertia can be calculated quickly according to the operation mode while considering whether the operation mode of an elevator is the powering operation mode or the regenerative operation mode. The control device for an elevator is equipped with a speed command input unit which inputs a speed command to a power device, a speed detector which detects the actual speed of the power device, and a torque controller which operates the required torque based on the speed command and the actual speed and drives the power device by outputting a torque signal. The control device is further equipped with an initial parameter setter which presets the initial values of parameters of the torque controller, an operation mode decision unit which decides whether the operation mode of the power device is the powering operation mode or the regenerative operation mode, an inertia calculation unit which calculates the actual inertia value based on the speed command, the actual speed and the torque signal and the operation mode, and a parameter correction unit which corrects the parameters of the torque controller by using the actual inertia value. |
