摘要： A motion control method comprising receiving a motion request to move the lens module from an initial position to a final position, determining a middle position between the initial position and the final position, determining an initial parameter value, a middle parameter value and a final parameter value based respectively on the initial position, the middle position and the final position, estimating a parameter uncertainty based on a maximum value and a minimum value wherein the maximum value is the greatest value among the initial parameter value, the middle parameter value and the final parameter and the minimum value is the smallest value among the initial parameter value, the middle parameter value and the final parameter and selecting a type of input shaping signal based on the estimated parameter uncertainty.
