Moreover, concerning the speed estimation for the PMSM rotor, the performance of a Sliding Mode Observer (SMO) type observer is improved by using a Phase Locked Loop (PLL) control technique. The control performance of the sensorless control system is improved by optimally tuning the parameters ...
Sensorless Field-Oriented Control of PMSM Implements the field-oriented control (FOC) technique to control the speed of a three-phase permanent magnet synchronous motor (PMSM). For details about FOC, see Field-Oriented Control (FOC). Ports ...
This brief proposes an iterative sliding mode observer (ISMO) for the robust sensorless control of a permanent magnet synchronous motor with variable parameters. In the conventional SMO, a low-pass filter and an additional position compensator for the rotor are used to reduce the chattering coming ...

Because of its low-chattering character, a LPF is not necessary for STSMO, which means the observation of back-EMF can directly be the input of PLL. The structure of PLL and PMSM sensorless control system based on STSMO is shown in Figs. 1 and 2 respectively, in which nref is the re...
