Based off my line follower there are·a few things you can do to make it work better.

First - if you are using only one sensor on each side of the line it will get jerky. To overcome this use another sensor closer to the outside of the robot. What this allows for is the first sensor to cross the line and make a small correction and if the second sensor crosses the line make a bigger correction. The more sensors you use the less jerky the movments.

Second - if you can't do the first suggestion try changing how much of a direction change occurs and how fast it happens.

Third - if you are using a servo for steering govern it by a ration instead of a straight turn setting. If you are using motors shorten the time they are on based on a variable setting. This means a smoother turn when a turn occurs. If you don't like those results have it move in small increments.
