Abstract :
In this paper, the sensorless control of the interior permanent magnet synchronous motors using the sliding mode and the binary observers are compared. Also, the structure of the above observers only uses the voltage equation. Since the parameters of the dynamic equation such as machine inertia or viscosity friction coefficient are not well known and these values can be easily changed during normal operation, there are many restrictions in the actual implementation. In order to estimate the rotor speed and position, the Lypunov function is used. The performances of each observer are confirmed by the experiments.
