Systems and methods of driving a nacelle to a target nacelle yaw position are provided in which an auxiliary yaw position control system is coupled to a turbine control unit. The auxiliary yaw position control system receives a first signal representing a current nacelle yaw position and a second signal representing a target nacelle yaw position. The auxiliary yaw position control system determines, based upon the current nacelle yaw position and the target nacelle yaw position, whether and in which direction the nacelle needs to move to be in the target nacelle yaw position and sends nacelle yaw actuation signals to the turbine control unit. If it is safe to accept the nacelle yaw actuation signals, the auxiliary yaw position control system commands the yaw drive so it moves to the target nacelle yaw position.

Embodiments disclosed may serve the function of a pump, a generator, or a propulsion system. Two flexible fins are coupled via their longitudinal inner edges to fin coupling modules. An external fluid flow causes traveling fin undulations. The angle of the fins relative to each other changes as undulations travel along the fins which can be translated through the fin coupling modules into mechanical work, powered by the external fluid flow. The mechanical work of the fin coupling modules may be the cyclical extension and contraction of pistons or bellows incorporated into the fin coupling modules, which may draw ambient fluid during their extension cycles and compress fluid during their contraction cycles to create a pump. The pistons or bellows may also be sealed from ambient fluid but connected through conduits through which contained fluid is exchanged in a continuous circulation of fluid to power a pump or a turbine.
