Abstract:
A movable barrier system allows for varying the linear actuator speed to account for speed variances caused by the physical configuration of the system. An example system includes a processor configured to variably control operation speed of the linear actuator when it moves a movable barrier between a first position of the movable barrier and a second position of the movable barrier as a function of location of the movable barrier pivot connection relative to the linear actuator pivot connection. The function may be a function of a ratio of a distance from the linear actuator pivot connection to a fixed point and a distance from the movable barrier pivot connection to the fixed point. The function may be calculated by the processor or accessed by the processor according to information about the physical configuration of the system.
