چکیده
|
In this paper, an adaptive nonlinear controller is designed for rotor surface permanentmagnet synchronous motor (spmsm) drive on the basis of input-output feedback control (lofc),and recursive least square (rls) method. the rls estimator detects the motor electromechanicalparameters, including the motor iron loss resistance online. moreover, a sliding-mode (sm) observeris developed for online estimation of the rotor speed and rotor position. in this control scheme, thetorque reference signal is generated by a conventional speed pi controller. the effectiveness andfeasibility of the proposed control approach is tested by simulation. computer simulation results showthat the errors in the estimated quantities asymptotically converge to zero. these results also showthat the drive system is stable and robust against the parameter uncertainties and external load torquedisturbance.
