The study focuses on wind flow energy harvesting technology utilizing the vibration method. The one-degree-of-freedom mathematical model comprises a flat plate connected to a foundation via an elastic element, subjected to airflow induced by the wind. Energy accumulation occurs within a generator. The braking force exerted by the generator can assume a constant, linear, or non-linear relationship with plate velocity. Oscillation motion is induced by altering the plate area within each oscillation cycle, with maximum area exposure to the windward motion and minimum during leeward movement. Control switches, functioning as level functions, facilitate motion synthesis and simulation by simplifying the description of plate area and generator switching control in the phase plane. Additionally, a control switching delay is introduced for plate area variation, described in terms of velocity and coordinate levels. The paper presents computer simulation results in the form of phase diagrams and time responses, followed by an analysis of generated power and energy extraction efficiency.
