Harmonic Current Suppression for Dual Three-Phase PMSM Based on Deadbeat Control and Disturbance Observer

IEEE transactions on industrial electronics (1982. Print), 2023
Harmonic currents always exist in a dual three-phase permanent magnet synchronous machine due to the inverter nonlinearity, nonsinusoidal back-electromotive force, and external disturbances.

Disturbance observers for general exogenous disturbances

2019 IEEE International Conference on Mechatronics and Automation (ICMA), 2019
We examine a parameterization of linear disturbance observers for general exogenous disturbances. Using the states and inputs of the system as variables, we got an parameterization of linear disturbance observers for general exogenous disturbances in frequency domain formulation.
