Application of a programmable logic controller in industrial washing machines
(Igor Sikorsky Kyiv Polytechnic Institute, 2024) Yan Zeng; Toropov, Anton
The dissertation is devoted to the development of an optimal control system for the electric drive of the rotation of the drum of an industrial washing machine. The principles of construction of control systems for an electromechanical system with a significant eccentricity of the load are considered, the features of their operation are determined. An updated model of the electric drive of the washing machine with a significant nonlinearity of the load moment has been developed. The optimal drum speed controller was synthesized by the method of dynamic programming, consisting of the sum of linear and cubic components. The study of the system's performance was carried out by the method of digital modeling using the MATLAB mathematical environment and its Simulink application. A startup project has been developed for the implementation of a PLC-based washing machine control unit.
