Abstract

The invention discloses a motor position overshooting control method and a control device. The motor position overshooting control method includes: receiving a target position value needing to be reached by a motor and inputted by a user; determining a first position curve according to the target position value and preset parameters, a current position value, a current angular speed and a current angular acceleration of the motor, wherein the first position curve is a motor rotation angle curve corresponding to the motor rotation time, the starting position of the first position curve is the current position value of the motor, and the ending position of the first position curve is the target position value of the motor; and controlling the motor rotation angle according to the first position curve to enable the motor to reach the target position value. The method solves the problem of motor position overshooting, and position precision during motor rotation is improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a method and a control device for controlling motor position overshoot. Background technique [0002] At present, AC asynchronous motors, permanent magnet synchronous motors, etc. are all equipped with a control device and a client connected to the control device. The client is used to receive the position target value input by the user, so that the control device makes the motor Rotate to reach the corresponding position. In actual operation, if the position target value is very large, the control device adjusts the rotation angle parameter according to the position target value to make the motor rotate at the maximum speed and acceleration, so that the motor can quickly reach the position target value. However, a motor rotating at maximum speed and acceleration often suffers from position overshoot after reaching the position target value. [0003] Such as figure 1 as shown, ...
