The invention provides a synchronous control method and device for a double-shaft integrated driver, and the method comprises the steps: calculating a first-shaft speed instruction reference value Vref1 and a first-shaft current instruction feedforward value Tfwd1 according to a first-shaft position instruction reference value Pref1, a first-shaft position feedback Pfbk1, and a second-shaft position feedback Pfbk2; according to the 1-axis speed instruction reference value Vref1 and the 1-axis actual speed Vfbk1, a 1-axis current instruction reference value Tref1 is calculated; an output voltage U is calculated according to the first-axis current instruction reference value Tref1, the first-axis current instruction feedforward value Tfwd1 and the first-axis actual current Tfbk1, the output voltage U is used for controlling a motor to rotate, and the problem that in the prior art, after one axis gives a fault alarm, the other axis cannot conduct synchronous following stop is solved. 本申请公开提供了双轴一体驱动器同步控制方法及装置，其中，
