This paper addresses the robust stabilization problem of a permanent magnet synchronous motor (PMSM). In order to optimize the speed-control performance of the PMSM system with different disturbances and uncertainties, Sliding mode control design for the PMSM is developed. We discuss in this paper how to achieve and maintain the prospective benefits of sliding mode control (SMC) methodology combined...
A robust nonlinear disturbance observer based control (NDOBC) approach is proposed for a permanent magnet synchronous motor (PMSM) drive system which is supposed to experience mismatched parameter perturbations as well as unknown load torque disturbances. The proposed control method is expected to obtain fine robustness against parameter uncertainties and external disturbance attenuation performance...
In this paper, a robust sensorless speed observer-controller scheme for a permanent magnet synchronous motor (PMSM) is proposed. To estimate both position and speed, without any mechanical sensors and only from the electrical measurements, a back-EMF-based sliding mode is designed. The convergence of this observer is proved. Then a high order sliding mode controller is developed. By using this technique,...
This paper presents a cascaded nonlinear predictive control of a permanent magnet synchronous motor (PMSM) drive. The Taylor series expansion is used to carry out the prediction defined on a finite horizon. However, it's well-known that this control strategy cannot remove completely the steady state error under mismatched parameters and load torque. Then, the full knowledge of machine parameters and...
An robust control scheme on the model of surface permanent magnet synchronous motor, composing a sliding-mode controller and a sliding-mode observer, was presented in this paper. To eliminate the effects of parameters variation and uncertainties, the controller was constructed instead of conventional PI controller as well as the self-adaptive rule was deduced using Lyapunov stability theory. The required...
