Abstract
A general scheme for calculating a solvability set (backward reachability set) is proposed for a linear conflict controlled system. The backward procedure constructs each subsequent set only based on the set from the previous step. The algorithm is specified for a target set with a convex complement (concave target set). The concavity of solvability sets is justified for a concave target set. The conservation of the concavity singles out a separate class of time-optimal differential games. Note that the convexity is not conserved in the general case of linear time-optimal differential games. On the whole, the article deals with a theoretical approximation of solvability sets in linear time-optimal conflict control problems, the construction of which with structural accuracy (allowing one to distinguish barriers) is usually nontrivial even on a plane. The algorithm is illustrated by numerical calculations for two disturbed dynamics with concave target sets in the plane: the double integrator and the oscillating system.
