Abstract
A closure system for controlling speed of a closure member, where the closure system includes a controller for transitioning speed of a closure member being operated in response to an obstacle being sensed in the path of the closure member. In one embodiment, a linear speed control algorithm determines the speed transitioning. In response to sensing contact with an obstacle, the controller may use a conventional contact process to stop or reverse the closure member. The closure system provides for a higher closing velocity of the closure member than conventional closure systems.
