A method to determine gain matrix of stator flux full order observer;

A novel modulation scheme for matrix converters of doubly-fed induction genrerators based on stator flux

A stator flux oriented control method of the PMSM based on the SVPWM is presented in this paper, with which a full digital PM AC servo system based on the DSP is developed.

The paper introduced the based principle on asynchronous motor DTC and set up Stator flux linkage and electromagnetics torque math model underα-βcoordinate axis and was simulated by Mat- lab/Simulink,simulation results prove the model is correct.

With the method,a perfect circluar track of stator flux linkage and a low torque ripple can be implemented.

Some calculation methods of stator flux linkage of induction motor are analyzed, discusses their essence and advantages or disadvantages are chscussed.

The paper introduced the vector control technique oriented by the stator flux of the generator, whic.

The basic theory of the AC excited VSCF wind power generation system and the vector control technique oriented by the stator flux of the generator was introduced.

This paper analyses a doubly\|fed vector control system built in the stator flux linkage orientation; by adjusting the three plase current and voltage in the rotor, the active power and reactive power is controlled by independent; the control method of the active power and reactive power is described; and then the system block diagram based on IBM\|PC is given.

By testing different wind speed, rotor speed reference of machine was given and the stator-flux oriented control strategy was used to control active and reactive power of machine independently and realize maximal wind energy capture.
