This paper proposes a composite control strategy which combines a discrete-time sliding mode controller with a disturbance observer aiming to decouple current control of vector oriented induction motor drives. The stator current control is carried out through an indirect field orientation in a dq reference frame rotating at synchronous speed. The cross-coupling variables of the induction motor stator...
This paper presents a current control method applied to permanent magnet synchronous motors using sliding mode controller and disturbance observer. The current control is carried out at dq synchronous reference frame. The proofs of stability are developed from the Lyapunov analysis requirements. A sliding mode rotor speed observer is combined with the proposed current control scheme. Simulations results...
This paper proposes a combined control strategy using a sliding mode controller and a disturbance observer applied to the current control of the permanent magnet synchronous motor. This scheme provides the stator current decoupling in the synchronous reference frame dq, minimizing the non-modeled disturbances effect, parametric variations and the phenomenon chattering characteristic in sliding mode...
This paper presents a decoupled current control system applied to induction machine drives via sliding mode control and disturbance observer. The current control of induction motor is carried out with indirect field orientation rotating at dq synchronous reference frame. The coupling terms are modeled as disturbance and the observed disturbance is used in the control law. Moreover, an algorithm aiming...
