| 摘要 |
An elevator system includes a microprocessor-based cab controller mounted directly on an elevator car, which controls elevator door motion in response to the difference between elevator door velocity and a desired dictated door velocity. The signals driving the elevator motor include compensation signals for hoistway door spirators, static door friction, and variations in the door operator mechanism as a function of door position, and are generated, in the disclosed embodiment, to take into account the variation in door motion as a function of door motor motion. An exemplary elevator system, an exemplary microprocessor-based controller, and logic flowcharts for an overall door control program, as well as details of the invention herein are disclosed.
