The control problem is the problem of regulating some process in order to achieve some control goals. Examples can be from economics, spaceflight, medicine, robotics, etc. A mathematical theory can be established if the control resources and the control goals are quantified.
 The most basic, and still one of the most challenging control problems  is the output regulation of a black box with a single (numeric) control input and a single (numeric) output. The mathematical model  of  the process is not available, and only some basic assumptions are  postulated.
 The presented strategy is based on the theory of homogeneous sliding  modes. The control can be done as smooth as needed. It is produced in  real time basing on a number of the real-time-calculated time derivatives of the output. The same control is demonstrated to be  efficient in keeping a car to a given route and regulating the blood  glucose level of a living rat. Finite-time-exact arbitrary-order  real-time differentiation is demonstrated that is robust to unmodeled  input noises, delays and digital errors.
 The proposed universal control algorithms are ready to use, do not  require much calculations, and can be easily applied without understanding the underlying mathematical theory.
