Modeling and Analysis of Multi-motor Drive Properties in a Web Processing Continuous Line

One of the main objectives in web handling machinery is to reach a pre-set web speed while maintaining the constant web tension in sections of continuous processing line. The paper presents model of a multi-motor drive system in the continuous web-processing line where the motors driven the working rolls are mutually connected by elastic coupling caused by processed web. Control algorithms of such industrial application with the multi-motor drive system are advantageously verified by simulation. This enables to test driving system properties at large dynamic variations that occur commonly in such web tension applications. Results of the simulation show correctness of the developed control system algorithms with data of a real production line.
