Problems solved by technology

[0002] In tobacco, logistics and other industries, actuators are generally sampled to transport goods. During the movement of the actuator, due to inertia and other reasons, the actuator slips during the movement, resulting in inaccurate position operation.
[0003] When the prior art solves this problem, the position is constantly adjusted when the position is inaccurate
During the adjustment process, the actuator may continue to slip due to inertia and other reasons, resulting in the actuator needing to repeatedly vibrate back and forth several times before it can adjust to the target position, which will take a long time to adjust and seriously affect the operating efficiency of the actuator

Abstract

The invention provides an operation control method and device of an execution mechanism, and belongs to the technical field of motor control. The method comprises that a present theoretical distance achieved by the execution mechanism according to operation of a motor and a present practical distance collected by a position collector are obtained; a present target operation distance that needs tobe achieved by the execution mechanism according to operation of the motor is re-determined according to the present theoretical distance and present practical distance; a present operation state of the execution mechanism is determined according to the present target operation distance; and a moving speed that needs to be achieved by the execution mechanism is calculated according to the presentoperation state, and the rotating speed of the motor is adjusted according to the moving speed. The present target operation distance is re-determined by updating the target operation distance in realtime in the operation process, the execution mechanism can be controlled to move to a required target position accurately instead of being adjusted to the target position via repeated oscillation, and the operation efficiency of the execution mechanism is improved.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to an operation control method and device of an actuator. Background technique [0002] Tobacco, logistics and other industries generally sample the actuator to transport goods. During the movement of the actuator, due to inertia and other reasons, the actuator slips during the movement, resulting in inaccurate position operation. [0003] When the prior art solves this problem, the position is constantly adjusted when the position is inaccurate. During the adjustment process, the actuator may continue to slip due to inertia and other reasons, resulting in the actuator needing to repeatedly vibrate back and forth several times before it can adjust to the target position, which will take a long time to adjust and seriously affect the operating efficiency of the actuator. Contents of the invention [0004] In view of this, the object of the present invention is to provide an ...
