Polytope techniques do well in controlling constrained system control but the complex geometric computations for some systems prevent them from being widely used. For such problems, the simplified algorithm based on computations of polytopes, is proposed in this paper. The computations are simplified by optimizing the algorithm for computing the level sets. For the problem of increase in time caused by the spaces lost in the process of simplification, a new method for computing the control inputs is proposed. The results of the simulation show, that computations with the new algorithm are much simpler than polytope techniques, the control time is shorter than in ellipsoidal techniques and the range of control is higher.
