Title: Solar tracker control system and method

Abstract

A pneumatic control unit configured to inflate a first and second set of bellows with fluid from a pneumatic fluid source via a pneumatic circuit, the first and second set of bellows associated with one or more pneumatic actuators. The pneumatic control unit determines a target configuration of the actuators based on a determined current position of the sun; determines a current configuration of the actuators; determines a difference between the determined current configuration and target configuration of the actuators; determines that the difference between current configuration and the target configuration of the actuators is outside of a tolerance range; and actuates the actuators toward the determined target configuration by at least one of inflating the first or second set of bellows with fluid from the pneumatic fluid source via the pneumatic circuit.
