Abstract:
1. A motor control method comprising the steps of: performing a speed feedback control of a motor such that a speed of a body driven by the motor is consistent with a predetermined target speed, and generating a deceleration directive corresponding to time elapsed since a predetermined deceleration control start timing as the target speed using a deceleration function of the elapsed time, to perform the speed feedback control based on the generated deceleration directive, during a deceleration control period in a driving period, the driving period being from when the body starts to be driven until it is stopped, the deceleration control period starting from the deceleration control start timing and ending when the driven body is stopped, wherein the deceleration function is a function which monotonically decreases from the deceleration control start timing until the deceleration directive becomes zero (0) and of which derivative is a monotonically decreasing or increasing function or a constant.
