Optimization-Based Collision Avoidance [PDF]

open access: yesIEEE Transactions on Control Systems Technology, 2021
This paper presents a novel method for reformulating non-differentiable collision avoidance constraints into smooth nonlinear constraints using strong duality of convex optimization. We focus on a controlled object whose goal is to avoid obstacles while moving in an n-dimensional space.
