- © 2020 John Wiley & Sons, Ltd.A new dynamic output feedback control scheme for planned motion reference tracking on nonlinear permanent-magnet synchronous motors in presence of uncertainty is proposed. Parametric uncertainty, unmodeled dynamics, and variable mechanical load torque are considered as time-varying unknown signals to be suppressed actively by control voltage inputs. Dynamic feedback of output signals to be controlled are only required to perform entire planned motion tracking. The control scheme can be performed on both classes of interior- and surface-permanent-magnet synchronous motors. Analytical and numerical results prove the effectiveness of the dynamic output feedback control method on multi-input multi-output nonlinear synchronous motors.
