EN A new branch of computational cybernetics seems to emerge on the principles akin to that of the traditional soft computing (SC). In the present paper the essential differences between the conventional and the novel approach are summarized. At the cost of the use of a simple dynamic model, a priori known, uniform, lucid, structure of reduced size, machine learning by a simple and short explicit algebraic procedure especially fit to real time applications considerable computational advantages can be achieved. The key element of the approach is the modified renormalization transformation supported by the application of a simple linear transformation, and the use of a simple prediction technique. It analyzes how the satisfactory conditions of the "complete stability" can be guaranteed, and the convergence properties can be improved by the ancillary methods. Simulation examples are presented for the control of a 3 DOF SCARA arm by the use of partially stretched orthogonal transformations.
