Hi
I'm new to LabVIEW and fuzzy logic. Being given a small problem to modify the backwards parking car example into a roundabout that the car goes around in a circle. Anyone know how I would go about accomplishing this or of any tutorials that would be similar? Something like in the picture is what I'm trying to accomplish .

Hi,
I think this tutorial might interest you. And also you can find other tutorials about fuzzy systems in the same page.
You can use circle formula ` (x−a)2 + (y−b)2 = r2 to make car go along a given trajectory.

Thanks for the reply. Would that be changed in this part of the program? The fourth line is really confusing me

Hi again,
Hope You are doing well,
Yes the new position should be given in that part. You should give him parameters as new X Y position, Vehicle Orientation and Steering Angle. I
And here's one useful link about creating linguistic variables. And one link's about fourth line (New vehicle orientation)

A couple of considerations here:
Fuzzy systems would perform the following with possibly multiple fuzzy controls for step1 and the others (Steps 2-4 controlled by same table):

Thanks for your response I appreciate you taking the time to help me learn.
Since my last reply I have constructed my own system to replace the initial one. In mine the car will reverse or drive to the centre from any position and once there will start reversing in circle at roughly the mid-point. I didn't modify the LabVIEW program in anyway however. I tried changing the formula to somehow set a midpoint to replace the garage so the car would aim for that instead but to no avail. I can understand a Fuzzy System which is my goal so I'm happy with that but the LabVIEW program and formula editing still seem advanced for me.
