Abstract

In order to improve the stability of the engine driven self-excitation cage asynchronous generation system（EDS-CAGS） on the condition of the large range speed variation and the impact load

and to reduce the pulsation of thedirect torque control（DTC）

a new voltage space vector DTC is proposed based on the Super-Twisting control of the voltage-linkage outer subsystem and the K-class direct feedback linearization control of the current inner subsystem. EDS-CAGS simulation results show that

on the condition of the large-range speed variation and the impact load

compared with the traditional voltage outer-loop and current inner-loop DTC method

the overshoot of the DC output voltage is reduced significantly

the response speed of the torque is fastened

the derivative values of the sliding mode variables can be converged

and the robust stability of the EDS-CAGS is enhanced by the new Super-Twisting sliding mode control method.
