This study suggests a co-evolutionary method for solving pursuit-evasion games with consideration of non-zero lethal radii. The proposed method has three key features. First, it can handle both the final time problem and the miss distance problem simultaneously, by adopting a separated payoff function. Second, the Stackelberg equilibrium instead of the(More)
In this paper, a closed-loop switching function for on-off thruster firings is proposed to provide good attitude control performance in the presence of modeling errors for single-axis slew maneuver of a rigid spacecraft and to eliminate double-sided thruster firings. The size of a single-sided deadband in the switching function provides the capability of a(More)
