Maximum torque/current control of 2-phase hybrid stepping motor

In this paper, the control strategy of the maximum torque/current method is presented after the mathematical model of the 2-phase hybrid stepping motor is analyzed. And a space-voltage vector pulse width modulation (SVPWM) method is put forward based on the 2-phase hybrid stepping motor driven by H-bridged circuit simultaneously. At last, experiments of the double closed-loop control system of the 2-phase hybrid stepping motor are carried out and results of experiments are given.
