The present invention relates to a method and apparatus for precise control of a position of a servo motor based on space-time two-dimensional optimization. The method includes the following steps: targeting either one of an angle or a displacement of the motor as a target value; obtaining a set value and a feedback value of the target value; based on the set value and the feedback value of the target value, performing processing by a control algorithm integrating a time dimension and a space dimension to obtain an output of the target value at a time t in a k dimension; and performing corresponding control on the motor based on the output of the target value at the time t in the k dimension.
