Method and device for speed regulation of centrifugal machine, centrifugal machine and computer readable storage medium

The invention relates to the technical field of centrifugal machines, and discloses a centrifugal machine speed regulation method which comprises the following steps: determining that a motor of a centrifugal machine is in a stable stage or a speed regulation stage under the condition that a target rotating speed is regulated from an initial target rotating speed to a latest target rotating speed; under the condition that the motor is in a stable stage, controlling segmented speed regulation of the motor according to the initial actual rotating speed, the latest target rotating speed and the rotating speed point array of the rotating speed change curve; and under the condition that the motor is in a speed regulation stage, controlling segmented speed regulation of the motor according to the initial target rotating speed, the latest target rotating speed, the initial actual rotating speed and the rotating speed point array of the rotating speed change curve. The rotating speed is stably changed in the centrifu
