Undergraduate thesis: Linear control systems and the regularity of the minimum time functions
(May 31, 2015)
Advisor: Khai T. Nguyen
Abstract: Consider the linear control system with the target . The function is the minimum time needed to steer a point to . It is well-known that under the Rank-Kalman condition, is just continuous in the reachable set. Our main goal is to study the regularity of . We prove that is a.e. twice differentiable. Moreover, we also obtain an explicit formula for the set of singularities where the optimal control changes its sign.
