Interpolation Curves/Surfaces in FRC
So, I read another thread discussing methods of finding an equation for a given set of points, I wondered how or if other teams use interpolation tables as a quick and easy way of scaling data and getting a desired transfer function.
I attached two examples of 3d surfaces (both are from Kettering's FSAE engine software) and a 2d curve (from a robot).
In either case, the input breakpoints and output values at each cell are calibrated in a table. You can change things so the response is nonlinear, or if you have exact values at certain points you can type them in. The software then finds the correct cells bounding the input variables, and interpolates linearly to find the output.
I use them all the time, both at work and in FRC. Does anyone else use them. What are your thoughts?
