He covers sensors and electrical measurements, analog numerical control, models of asynchronous machines, speed variation, the tools of fuzzy logic, and diagnostics and signals pointing to a change.
From all the renewable energy electricity production systems, the wind turbine systems are the most used specially the doubly fed asynchronous machine based systems, the control of theses systems is particularly difficult because all of the uncertainties introduced such as: the wind speed variations, the electrical energy consumption variation, the system parameters variations, in this paper we focus on the robust control ([H.
Section 2 presents the wind turbine system equipped with the doubly fed asynchronous machine and then the mathematical electrical equations from what the system is modelled (in the state space form) are given.
The system use the wind power to drag the double fed asynchronous machine who acts as a generator, the output power produced must have the same high quality when it enters the electrical network, i.
The control of the asynchronous machine is studied in many papers and different publications (Garlasu et al.

The Simulink scope shows stator currents and speed of the asynchronous machine.
The control of the asynchronous machine is studied in many papers and different publications (Babescu et al, 2005, Abed, et al 2006) where complex control methods are proposed, with difficult practical implementation.
0 includes new models for electric machinery, such as a steam turbine and governor system, DC machine, synchronous machine with a salient pole or round rotor, and an asynchronous machine with a wound or squirrel cage rotor.
The same frequency converter can be configured for operation of standard asynchronous machines, permanent magnet and synchronous reluctance motors; even existing installations can be upgraded with the new software.
