Abstract (en)
An elevator control apparatus which performs velocity control by using a model arithmetic operation part is capable of high-following-capability control by predicting the inertia value of a control target. An elevator control apparatus (110) includes an inertia error prediction unit (80A). A first arithmetic operation part (81a) calculates a pre-convergent inertia error (intermediate value) based on integral arithmetic operation of a velocity deviation between a model velocity (É A ) and an actual velocity (É M ) of a period where an acceleration build-up state and a constant acceleration state of an elevator car are consecutive, and outputs the pre-convergent inertia error to a second arithmetic operation part (82a). The second arithmetic operation part (82a) predicts a post-convergent inertia error based on the intermediate value output from the first arithmetic operation part (81). Based on the post-convergent inertia error predicted by the second arithmetic operation part (82a), a parameter correction unit (90) corrects an inertia value (J A ) preset in a model arithmetic operation unit (30).
