Abstract: The invention converts wave energy into electrical energy. A device moved by wave action is coupled to an electric machine for generating electrical power and to drive the device to improve conversion of wave action into electrical power. The conversion of the wave energy is improved through real-time estimation of forces exerted by waves on a pendulum axis to estimate the force to be applied to the device by the electric machine acting as an electrical motor.

Abstract: The invention is a method of converting wave energy into electrical energy using a device comprising a moving device cooperating with an electric motor which oscillates with respect to the motor under the action of the waves.

Abstract: An apparatus comprises a brushless motor, driver, incremental displacement sensor, and processor. The motor has a rotor, stator, and electrical terminals accepting a drive signal. The initial phase of the rotor is unknown. The driver is connected to the electrical terminals and produces the drive signal. The displacement sensor is configured to measure a displacement of the rotor and to produce an output signal. The processor has an input receiving the output signal and an output connected to the driver. The processor causes the driver to produce the drive signal according to a predetermined function of time, observes the output signal from the displacement sensor resulting from the drive signal, and performs mathematical computations on the basis of the observed output signal and a model of dynamic behavior of the motor to estimate the initial phase of the rotor.
