Fixed-Time-Convergent Sliding Mode Control with Sliding Mode Observer for PMSM Speed Regulation. [PDF]

open access: yesSensors (Basel)
This paper focuses on the speed control of a permanent magnet synchronous motor (PMSM) for electric drives with model uncertainties and external disturbances. Conventional sliding mode control (CSMC) can only converge asymptotically in the infinite domain and will cause unacceptable sliding mode chattering.

Chattering suppression of the sliding mode observer for marine electric propulsion motor based on piecewise power function

open access: yesFrontiers in Energy Research, 2022
The sliding mode observer (SMO)–based sensorless control is essentially a discontinuous switching control algorithm. Therefore, there is large speed or torque chattering in the permanent magnet synchronous motor (PMSM) with existing sliding mode observer–
