The invention relates to a method of determining internal temperatures () (coil and magnet temperatures) in a synchronous electrical machine () using state observers for the resistance of the coils and the magnetic flux of the magnet. The invention also relates to a diagnostic method, a control method and system () for controlling a synchronous electrical machine from the internal temperatures thus determined.

Method and system of internal temperatures determination in a synchronous electrical machine using state observers

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.
