This paper proposes a sensorless high-order super twisting sliding mode control method for induction motor speed servo systems. Based on the vector control principle, high-order super twisting sliding mode controllers in speed loop, current loop and flux loop are designed respectively. The super twisting sliding mode control is utilized to improve the response speed and robustness of motor control...
This article discusses the modeling and control wind energy conversion system WECS, equipped by a double fed asynchronous generator, which use the topology that stator is connected direct to the grid while the rotor is connected to grid through a back-to-back converter. The control strategy is applied to control active and reactive powers of the rotor side converter RSC with linear PI controller....
This paper present a combined field orientation and backstepping control. This method is an elegant approach for nonlinear super twisting sliding-mode control of an induction motor. The objective is to improve the speed control, the rotor flux control and the rejection of load torque disturbances and parameter variations. Simulation results are given to show the performance obtained with this kind...
This paper presents modeling and control of an electric vehicle based on second order sliding mode control using super twisting algorithm. This algorithm allows reducing the chattering phenomenon that appears in a classical sliding mode control. Simulation results are presented to show the effectiveness of the proposed control method for current and speed control.
This paper presents the nonlinear control strategy for high performance doubly fed induction generator driven by wind turbine. In the DFIG topology the stator is connected direct to the grid while the rotor is connected to a back-to-back converter. A simple and general space vector PWM algorithm is proposed. First, we propose a modeling of wind turbine and DFIG in the dq reference frame. Next, a field...
