Building on the CasADi infrastructure, we created an abstraction for the differentiation and evaluation of N-dimensional symbolic BSplines.
By parametrizing a function as a linear combination of positive basis functions (bspline), we can transcribe infinitely-dimensional positivity constraints on a domain to a finite set of positivity constraints on bspline coefficients.
In this talk, we demonstrate how this technique can be applied to 1) path constraints in a continuous-time optimal control problem, 2) robustifying constraints in a non-linear program, and 3) construction of smooth interpolating functions with desirable properties.
