Control method and system for improving current tracking capability of motor

The invention belongs to the technical field of motor control methods, and particularly relates to a control method and system for improving the current tracking capability of a motor, and the method comprises the steps: carrying out the feedforward calculation of a given motor current on the basis of a proportional-integral controller, and carrying out the feedforward of the given motor current to a control motor voltage for numerical correction, the deviation between the current output to the motor and the given motor current is effectively reduced, so that the current tracking capability of the motor in operation is improved, the hysteresis of motor position tracking is reduced, and the position error of the motor in operation is reduced. 本发明属于电机控制方法技术领域，具体涉及一种提升电机电流跟踪能力的控制方法及系统，本发明在比例积分控制器的基础上，将给定电机电流经过前馈项计算后，前馈到所述控制电机电压进行数值修正，使输出到电机的电流与给定电机电流的偏差有效减小，从而提高了电机在运行中的电流跟踪能力，并且电机位置跟踪的滞后性减小，减小了电机运行中的位置误差。
