Abstract—The paper proposes a method for creating of adaptive automatic control systems based on the method of task separation and combination of solutions proposed by the authors. At the first stage, the task of designing an adaptive system is divided into subtasks, which are solved using robust regulators. At the final stage, decisions can be partially combined or simplified by gluing solutions that are not significantly different, i.e. applying the same solutions in related situations. With the help of numerical modeling and optimization, the effectiveness of the proposed method has been demonstrated using an illustrative example. The method greatly simplifies the task of designing adaptive systems and their implementation.
