For the prey-predator model, an extended set of bounded finite-time stabilizing positional controls is given. We use Korobov’s controllability function $\Theta(x)$ which is a Lyapunov-type function. Previously, the controllability function was the unique solution of certain implicit equation on $\Theta$. In the present talk, we consider the case when there are between one and three solutions of the mentioned implicit equation. This occurs for initial positions belonging to certain domain of the phase space.
