The feedback system can keep the ball on the center. I once saw a talk by Prof. Cannon of Stanford and Caltech about the vertical pendulum which is similar to this.
You can use optical means to determine the ball position. The problem Prof. Cannon had was the hysteresis in the setup using low cost material. This ruined the stability.
The entire mechanical structure had linear and rotational parts that were not perfectly matched in their connections. The minute slop in the fittings caused problems.
