The invention discloses a method for adaptively adjusting torque control of a permanent magnet synchronous motor. The method comprises the following steps: 1) estimating a current actual torque of the motor based on a working condition; 2) calculating a difference value between the actual torque and the target torque; and 3) when the duration of the torque of the permanent magnet synchronous motor for maintaining the larger control error is not less than an adaptive adjustment time threshold, performing adaptive adjustment on the control target torque of the permanent magnet synchronous motor according to the following steps: 3-1) calculating an initial direct-axis self-adjustment parameter id-init and a quadrature-axis self-adjustment parameter iq-init; and (3-2) filtering the initial self-adjusting parameter, and calculating a direct-axis filtering self-adjusting parameter id-grad and an alternating-axis filtering self-adjusting parameter id-grad. According to the method, the actual torque ...
