Abstract-Electronic line-shafting control has demonstrated very promising features when applied to paper machine drives. To apply this new control methodology, it is necessary to develop a starting procedure for each individual section and a method for setting the parameters of the virtual line-shaft drive and in-shafts. This paper proposes and evaluates startup and commissioning procedures for electronically line-shafted paper machine drives. The procedure for acceleration of the individual sections is implemented using virtual variable-ratio gearboxes that emulate the physical clutches and conical pulleys used in the era of line-shafts. System stiffness is implemented using virtual in-shafts with active damping. Evaluation shows that the proposed virtual clutch/conical pulley assembly and active damping allow smooth acceleration of each section and maintain well-behaved response during load disturbances for all operating conditions, even with different numbers of sections effectively connected.Index Terms-Active damping, active differential damping, differential motion control, electronic line-shafting control, paper machine drives, synchronized motion control, virtual line-shafts.

“…In [6], an optimal synchronization for high-precision motion system was designed by introducing coupling and synchronization factors into the synchronization error. Many other control strategies have been adopted in this field, and they include adaptive control [7]- [9], fuzzy control [10], [11], electronic line-shafting control [12], [13], robust control [14]- [19], neural network control [20], gain-scheduled control [21], and model-free control [22].…”

This study focuses on the coordination control problem of multiple electrical excited synchronous motor systems. A robust coordination controller is designed on the basis of cross coupling and an interval matrix. The proposed control strategy can deal with load uncertainty. In addition, the proposed control strategy is applied to a high-power metal-rolling system. Simulation and experiment results demonstrate that the proposed control strategy achieves good dynamic and static performance. It also shows better coordination performance than traditional proportional-integral controllers.

“…Anderson R.G. et al [21] proposed the concept of "electronic virtual line-shafting". The sum of electromagnetic torque from the servo motors was taken as the load torque of the main motor, which can reduce the synchronization error caused by the starting delay, but the starting time was longer.…”

Abstract:Regarding the shortcomings of the cross-coupling control structure during the start-up of a multi-motor with load-namely, a large synchronization error and a long start-up time-this paper proposes a fuzzy self-adjusting cross-coupling control structure. This structure combines a fuzzy self-adjusting filter and an advanced synchronization compensator. The fuzzy self-adjusting filter adjusts the "softened speed", a newly established concept, so that each motor follows the trajectory of the softened speed during start-up, thus effectively reducing the synchronization error of the starting process. The advanced synchronization compensator is added to shorten the adjusting time of the motors. In addition, this paper analyzes the synchronization performance of the structure when the steady state is interrupted by a sudden step of load. Finally, this paper establishes an experimental platform for a synchronous speed control system for a permanent magnet synchronous motor, and verifies the effectiveness of the proposed structure and the correctness of the theoretical analysis through performing experiments.
