the teb planner give unreasonable constantly changing path

edit

I want to use TEB local planner algorithm to replace the DWA local Planner algorithm. I followed the course "Configure and run Robot Navigation"(http://wiki.ros.org/teb_local_planner/Tutorials/Configure%20and%20run%20Robot%20Navigation)

there is no warning or error print but the problem is when the real robot start to move the local path would chang too frequent and most of the time it make the robot rotate big angle.Beside it may sometimes produce an Opposite direction to the global path.

I follwed the solutions in"frequently asked questions "http://wiki.ros.org/action/fullsearch/teb_local_planner/Tutorials/Frequently%20Asked%20Questions?action=fullsearch&context=180&value=linkto%3A%22teb_local_planner%2FTutorials%2FFrequently+Asked+Questions%22 set global_plan_overwrite_orientation=falsebut it helpless

It is so sorry I can't upload to show my picture now,because lack of five points
