“…Multi‐motor speed synchronous driving system is widely applied in industrial field that requires high precision and high speed, such as printing, textile, chemical fibre, and so on. The speed synchronisation performance of multi‐motor system determines the reliability of industrial systems and the quality of products [1–4], and it is easily influenced by the driving performance and the load disturbances of the motors. Meanwhile, permanent magnet synchronous motor (PMSM) has been widely applied in high performance control field because of its high power density, high power factor and excellent control performance [5, 6].…”

This paper presents an improved relative coupling control structure for multi-motor speed synchronous driving system. Unlike the traditional relative coupling control structure, the proposed structure introduces an additional speed controller so that all the motors in the system can be treated as an entity. It also takes the importance of each motor's speed into consideration in the speed feedback process and the speed synchronous compensation. Meanwhile, the speed synchronisation and tracking performance of the multi-motor system can be decoupled (i.e. independently adjusted) and regulated by changing synchronous coefficient and tracking coefficient, respectively, and the performance of the multi-motor system can be obviously promoted. To evaluate the performance of the system comprehensively, this study proposes an assessment method based on synchronisation and tracking errors of the system, moreover, a comparison between the traditional structure and the proposed structure is analysed. Finally, the simulation and experimental results are carried out under triple-permanent magnet synchronous motor system, which can verify the feasibility and the effectiveness of the proposed method.

“…In recent years, many works have proposed some control methods to enhance tension control performance: sliding mode control (SMC) (Chen et al, 2004;Lu and Pagilla, 2014), H ' control (Dou and Wang, 2010;Kadik and Wang, 2012), data-driven control (Liang et al, 2014) and so on. Additionally, some control strategies without tension sensors can be found in Carrasco and Valenzuela (2006), Lin (2003), Lu and Pagilla (2014), Ponsart et al (2010) and Valenzuela et al (2003).…”

In this paper, a robust decentralized control scheme is proposed for web-winding systems. The control input for each subsystem is divided into two parts, a reference control input and a control compensation. First, the reference control inputs and the error dynamic models are presented. Then, based on the error dynamic model, a decentralized controller is designed to compute the control compensation, and the relevant sufficient condition for the existence of the decentralized controller is derived in terms of linear matrix inequalities (LMIs). By virtue of regarding some parameters as interval variables, the proposed controller has good robustness with regard to parameter variations and is adapted to the changes of set point. Finally, a three-motor web-winding system is considered as an application example, and simulation and experimental tests illustrate the effectiveness of the proposed controller.
