OPTIMIZATION OF DYNAMIC MODES OF A TECHNOLOGICAL LINE ASYNCHRONOUS ELECTRIC DRIVES COMPLEX
The paper researches and synthesizes a control system of an electric drive complex for a fiberboard painting line for the construction and furniture industries. The line is built based on variable frequency drives (VFD). To improve the quality of products, a uniform coloring and drying of sheets at all stages of the technological process was provided. As some of the line rolls were transferred to an individual drive and a positive feedback on the current of the stator in an VFD with sensorless control was introduced, the task of integrated control of electric drives of the color line and reducing the share of defects to 1-3 % was solved.
