Mathematical model of fuzzy control portal car wash
Incoming article date: 26.02.2018In the article on the basis of the analysis the basic technical and organizational actions are defined that allowed to carry out statement of a task on improvement of system of management of technological process of portal car wash. A mathematical model of fuzzy car wash control is developed due to the program control of water supply depending on the shape, geometry and degree of pollution of the car, in order to reduce water consumption and improve the energy efficiency of the portal car wash. Mamdani algorithm is proposed as fuzzy inference algorithm, which is easily implemented in MATLAB software product on the basis of knowledge and experience of experts, as well as modeling of the operator. Formalization of the description of water supply level, shape, size and degree of pollution of the car is carried out by means of linguistic variables, their type and description of elements of thermal sets of these variables is given. The proposed mathematical model can be used in the design of control systems and other types of automatic car washes.
