• Constructively verifiable sufficient conditions for speed-of-response-wise suboptimal guaranteed stabilization (in a finite time) when there is interference for one class of nonlinear control systems. A procedure is given for estimating the minimum guaranteed stabilization time. The synthesis of stabilizing control laws for the original nonlinear control systems of the class in question using the proposed approach is reduced (by means of a special choice of the construction of the control laws and nonlinear changes of variables) to the construction of game strategies for auxiliary linear conflicting-control systems. The nonlinear control laws so obtained are robust (stable) to errors and unallowed-for perturbations. Problems of the reorientation of a rigid body (a spacecraft) when there is interference is examined. Speed-of-response-wise suboptimal control laws are synthesized, and the results of computer modeling are given.
