Abstract: The disclosure belongs to the technical field of powered drive devices, and discloses an acceleration control method for a load on a powered backpack based on a disturbance observer. The method includes: S1 setting the desired acceleration of the load on the powered backpack, presetting the initial motor drive current that regulates the movement of the load according to the desired acceleration, measuring the actual acceleration of the load; S2 establishing the disturbance observer for controlling acceleration the load on the powered backpack, using the disturbance observer to calculate the motor drive current that makes the actual acceleration of the load equal to the desired acceleration, so as to realize the acceleration control of the load on the powered backpack.
