differential_drive_controller plugin causes robot rotation when cmd_vel changes

[DeepRowLie]

In the simulation, after the robot has been turning in circles for a long time, issuing a new control command will result in a slight rotation. This happens in ROS neotic, ubuntu 20.04 I published Twist messages, where only the x-axis linear velocity is greater than zero. Below is the trajectory of the robot. Below is my robot xacro
