Through to the asynchronous machine control system basic structure and the characteristic, non-cross couple multi-electrical machinery question and so on transmission system's fundamental type and characteristic research, unifies the monofilament extrusion transmission system widely to use the alternating current machine to actuate, the various axle loads perturbation difference major characteristic, proposed one kind of cross couple multi-electrical machinery transmission system structure, realizes the good dynamic property and the static property. In order to enhance the asynchronous machine non-velocity generator vector control system's performance, embarks from the SVPWM principle, the research electric current polarity distinction and the dead area compensating process, according to the voltage vector in the static coordinates' angle and the zipper machine power factor angle, calculate the current phasor in the static coordinates angle, thus obtains various interphase currents polarity, and has given one dead area compensating process.
