Abstract
A movable barrier system allows for varying a 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 an operation speed of the linear actuator as the linear actuator moves the movable barrier between a first position of the movable barrier and a second position of the movable barrier as a function of a location of a movable barrier pivot connection relative to a 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.
