Mathematically, the optimization for maximum power conversion will need to be performed under the additional constraint of maintaining the current levels of mixing while maximizing the energy extracted. At this time we have no method for predicting the subsequent evolution of marine habitats, thus the environmental cost of tidal power conversion is unknown. Aspects of the present invention may be embodied as a system, method or computer program product. The sensor system is connected to the foil members 20. In one embodiment, the sensor system is integrated, attached, incorporated, or embedded in whole, or in part, within the foil members 20. Also, the sensor system may incorporate the adjoint method. Moreover, the energy extracted is maximum at a mean angle of attack of about 15°, for an oscillation amplitude of 10°. Also, a gradient ascent algorithm is able to locate this optimum.
A real-time controller monitors the position and forces on the foil member 20 and maintains the system dynamics so that energy harvesting is accomplished at maximum efficiency. In one embodiment, the controller system comprises a computer and software for automatically manipulating the foil members to attain the one or more optimization objectives.

The operation of the foil members are optimized to attain one or more optimization objectives using a feedback control loop system. Referring to FIGS. 8-17, in operation, the foil members 20 are situated or immersed in the fluid flow 30 and are manipulated automatically to attain one or more optimization objectives in real-time operation. It should be noted that the one or more optimization objectives or the optimization algorithm are configured to be updated or modified.
A computer readable signal medium may be any computer readable medium that is not a computer readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device. This possibility recovers the recurring manual cost per installation of developing the optimum actuation stroke and makes the device site-agnostic to an extent. For example, when multiple such devices are deployed in vicinity of each other, the modified stroke need not be recomputed but the real-time optimization algorithm automatically accounts for the altered flow and perhaps even synchronizes the strokes for maximum energy conversion, without any manual intervention. In the latter scenario, the remote computer may be connected to the user’s computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider).

Such a propagated signal may take any of a variety of forms, including, but not limited to, electro-magnetic, optical, or any suitable combination thereof. A single turbine designed for the undisturbed site may become completely unsuitable as more turbines are installed and the local flow environment changes. In such tidal turbines, the flow of oncoming water deflects the turbine blades and because the blades are pivoted at the center of the turbine, causes them to rotate. A direct consequence of this property of the algorithms is that if the algorithm evolves the cyber-physical state towards temporary sacrifice, we are going to get an even more gain in benefits because the sum has to be positive. A design that is easily adaptable and does not need hardware tuning is economically desirable because then economy of scale can be used for reducing installation costs.
Although turbines also employ a streamlined geometry, the blade rotation means that the efficiency varies from the root to tip due to the change in local fluid velocity. The controller system or the feedback control loop system 28 may include a computer and software for calculating the algorithm with input from the sensor data and instructing the actuator system to manipulate the foil member 20, especially with regard to optimizing the stroke (FIGS. 6-7) of the foil member 20. Dolor en las articulaciones de las muñecas . In addition, embodiments of the controller may also include one or a multitude of internet based servers, and computer software, including internet web page based code, and methods of application for providing the user with an internet based service. The cyber-physical system 10 comprising one or more foil members 20 and a feedback control loop system 28. Cyber-physical systems are physical systems whose mechanical response is augmented by an onboard computer in response to real-time measurements, thus enabling enhanced artificial and even unphysical and intelligent behavior.

The computer readable medium may be a computer readable signal medium or a computer readable storage medium. A linking means may be provided for allowing the foil members 20 to oscillate within the fluid flow 30. In one embodiment, the linking means is a one or more gear mechanisms connected between the hydrofoil members 20 and the actuator system. Cyber-physical coupling between neighboring devices can be used to give rise to global oscillation patterns in the farm. We use the cyber-physical actuators to mimic springs, masses and dampers.
