 <content:encoded>&lt;div class='rss_texte'&gt;&lt;p&gt;The aims of this work, is the survey of the design and application of speed and flux&lt;br class='autobr' /&gt;
sliding mode controllers for vector control of an induction motor powered by a solar photovoltaic&lt;br class='autobr' /&gt;
energy. The solar photovoltaic energy nowadays, is one of the renewable energies sources present in&lt;br class='autobr' /&gt;
various domains of applications. Moreover, the photovoltaic generator (GPV) output voltage&lt;br class='autobr' /&gt;
depends of several climatic factors, such as the irradiations and the temperature. To overcome these&lt;br class='autobr' /&gt;
problems, one must carries out an adequate sizing and exploits the maximum power available at the&lt;br class='autobr' /&gt;
level of the (GPV). Thus the proposed structure in our work, is constitute of one (GPV) associated to&lt;br class='autobr' /&gt;
a (DC/DC) converter controlled by MPPT to fed an induction motor. After determining the&lt;br class='autobr' /&gt;
decoupled model of the motor, a set of simple surfaces and associated control laws have been&lt;br class='autobr' /&gt;
synthesised. A smooth control function with a threshold was chosen. However, the magnitude of this&lt;br class='autobr' /&gt;
control function depends closely on the upper bound of uncertainties, which include parameter&lt;br class='autobr' /&gt;
variations and external disturbances, and this generates chattering. So, this magnitude has to be&lt;br class='autobr' /&gt;
chosen with great care to obtain high performances.&lt;/p&gt;&lt;/div&gt;
