Observers Design For Sensorless PMSMs
Author:
Abstract: A state observer is proposed for permanent magnet synchronous motors (PMSMs). The gain of this observer involves a design function that has to satisfy some mild conditions which are given. Different expressions of such a function are proposed. Of particular interest, it is shown that high gain observers and sliding mode like observers can be derived by considering particular expressions of the design function. The simulation is given in order to compare the performance of a high gain observer and a sliding mode observer obtained through two different choices of the design function. Simulation is made by the software MATLAB/SIMULINK.
