WebThe Minimal Robust Positively Invariant Set for Linear Discrete Time Systems: Approximation Methods and Control Applications Abstract: This paper considers the minimal robust positively invariant set for linear discrete time systems and its robust positively invariant approximations. WebIn mathematical analysis, a positively (or positive) invariant set is a set with the following properties: Suppose x ˙ = f ( x ) {\displaystyle {\dot {x}}=f(x)} is a dynamical system , x ( t , x 0 ) {\displaystyle x(t,x_{0})} is a trajectory, and x 0 {\displaystyle x_{0}} is the initial point.
