Equivalent power method of reducing the affects of voltage variation during active material actuation

摘要

An equivalent power method for reducing the effects of voltage variation during at least one active material actuation event, includes determining an applied real output based on the ideal voltage of a voltage source, the corresponding ideal output of a controller, and a measured real voltage, and for providing voltage out of bounds compensation, by further determining a difference based on the maximum available power output of the controller during said at least one event, and applying the difference to determine the applied real output during subsequent event(s).
