Patent attributes
An actuated feedforward controlled solar tracker system including a sub-frame supporting at least one solar panel, a post supporting the sub-frame, and a linking mechanism connecting the sub-frame and post, where the linking mechanism includes a first axle, second axle and body member. The linking mechanism's first and second axles are disposed orthogonal to each other and are separated by the body member. The system includes at least two linear actuators, a rotational joint connecting the linear actuators and sub-frame, and a driver system that drives the actuators. Additionally, the system includes a feedforward control system including a computer that calculates desired positions of the linear actuators using multiple inputs and communicates with the driver system to drive the linear actuators, and a feedback control system that relays information gathered by sensor devices to the feedforward control system, where the feedforward and feedback control systems function in an integrated manner.
