Because of serious electromechanical coupling between the exciter and main machine,the threestage motor faces the problems of torque shock and dynamic start difficulties under the previous control strategy in the starting mode. A control strategy is proposed in this paper to solve the above issues. The main generator voltage vector amplitude was adjusted through sub-time closed-loop of current/speed,and the large inertia property of the aero-engine load was considered in this method. In this paper,regulatio...
