    On the nonlinear uniaxial reorientation problem for a three-rotor gyrostat in the game noise model

    Full text link
    We solve a nonlinear game problem of uniaxial reorientation for an asymmetric solid body with three flywheels (rotors). We give an estimate for admissible levels of uncontrollable noise depending on given constraints on controlling moments. © Pleiades Publishing, Ltd., 2012
