Finite-time stability involves dynamical systems whose trajectories converge to a Lyapunov stable equilibrium state in finite time. In this paper, we study the finite-time control of the ball impact system. First, finite-time stability of nonlinear continuous systems, hybrid dynamical systems and the definition of finite-time stability are mentioned. Then, we design the finite-time controller and analyze stability of the impulsive double integral system of the ball impact system. Finally, we give and analyze the simulation results of the system which verify the effectiveness of the finite-time controller.
