Abstract: This study presents the application of estimate techniques, in particular observer technique, in the diagnosis and the order without induction sensor engine. The engine with induction has the advantage of being robust, inexpensive and of simple construction. For these reasons it remains very appreciated and reliable for applications to high dynamic performances in the industrial world. The development of estimate techniques and microcontrôleurs appearance, DSP at low cost, for the data processing make engine with induction an exceptional actiner thanks to an excellent mass couple, a maximum reliability and a significant transitory surcouple. To preserve the correct operation of these systems, it is essential to supervise their operating condition in a continuous way. As a metter of fact the monitoring requires in its turn a set of apparatuses or measuring instruments, that are not alaways available, to provide data relating to the various operating modes from the system. Although the objective of this study is to reduce the number of measuring apparatus, for technological or economic reasons and consequently, sensors and wiring. This material is to be replaced by software built on the basis of estimator of states reducing in this way the cost of the installations and thus increases their reliability and automatically the output of production.
