Sensorless control of a flywheel enrgy strong system associated to an isolated hybrid energy production unit

Abstract EN

'The aim of this paper is to ensure the sensor less control of an inertial storage system associate to an isolated Hybrid Energy Production Unit (HEPU).

This isolated HEPU comprises t; solar/diesel, a Flywheel Energy Storage System (FESS) and a load.

The exceeded genen than required by the load is diverted towards a pump.

To maintain the wheel speegTiM operating range, a supervision strategy must be envisaged, thus ensuring the pMowuct, The nonlinear control with exact linearization for the flywheel squ ^ ^ ^ iimmctiJmim proposed.

Indeed, this control makes it possible to have a betterjmlfecoiAlingfbetween the two controlled variables which are the mechanical speed and the rotor fltakjfhe developed adaptive observer was integrated into the induction machine control with an accurl^} stability study.
