An assembly for generating electrical and thermal energy has a structure that supports a cogeneration device provided with a combustion engine supplied with fuel, an electric generator driven by the combustion engine, and at least one heat exchanger to heat a fluid for a thermal appliance using the heat produced by the combustion engine; the assembly also has a plurality of storage batteries, which guarantee the continuity of the flow of electrical energy during start-up of the electric generator and during load transients and are housed in a base of the structure.

The control device carries out a control of the induction machine based upon a flux estimation performed by means of a Luenberger state observer, the estimation error of which can be defined by means of a matrix having a plurality of eigenvalues, the magnitude of each of which is proportional to the magnitude of a respective pole of the induction machine, and the phase of each of which is rotated with respect to the phase of the corresponding pole of the induction machine by a given angle of rotation.
