Why does the turtlebot2 have a small angular velocity acceleration?

[LingyunLL]

When we used the turtlebot2 of the kobuki chassis, we found that when the control speed is sent to the /mobile_base/command/velocity topic, the angular velocity increases particularly slowly, which is much slower than the linear velocity increase. It takes about several seconds. How can I solve this problem?

Did you try to adjust PID gains in the ~commands/controller_info topic ?
