Method for controlling a device for converting wave energy into electrical energy

The invention relates to a method for converting wave energy into electrical energy using a device comprising a moving part that interacts with an electric motor, the moving part oscillating, relative to the motor, by means of the waves. The method consists of the following steps: a) selecting a law that expresses the position of the moving part on the basis of the force exerted by the motor on the moving part, and on the basis of the force of the waves applied to the moving part; b) actuating the motor in order to produce a specific force on the moving part; then c) measuring the position of the moving part relative to the motor over time; d) determining said force of the waves by using said law selected in step a) and by taking said specific force of the motor obtained in step b) and the position of the moving part measured in step c) into account; then e) determining a new value of the force exerted by the motor on the moving part, said new value corresponding to a force that maximizes the electric power recovered by the motor; and f) actuating the motor in order to generate the new value of the force determined in step e) by supplying electrical energy to the motor when the force of the motor drives the moving part and by recovering the electrical energy from the motor when the force of the motor resists the movement of the moving part.
