As already mentioned, the theoretical basis for control and regulation of entire machines or technological systems is mathematical logic, and therefore this section focuses on the repetition of certain areas of mathematical logic and the propositional and Boolean algebra. Application of laws and rules, the reader is familiar with the simplification of logic expressions. To find the mathematical expression verbal expression is introduced by one of the possible ways of using Karnaugh map. In chapter 3 also introduced the implementation of the mathematical formulation of technical means.
