“…For the filling production transmission system, this study takes the permanent magnet synchronous motor as the research object. In the ideal permanent magnet synchronous model [29], the vector control strategy of i d � 0 is adopted to obtain the state equation of the j motor in the multimotor system [30]:…”

To provide cooperative control under complex working conditions of a filling multimotor system, this paper proposes a relative coupling control strategy with a switching system structure. Firstly, a multistation transmission system composed of a filling motor and a transfer motor is designed according to different filling processes. Secondly, a stable sliding-mode surface common to the multimotor system is selected, and an equivalent sliding-mode controller corresponding to each motor is designed. Thirdly, public Lyapunov stability theory is used to prove that the switched system can move from any initial state to the common sliding surface of the system, thereby ensuring the asymptotic stability of the entire system. Simulation results show that this method has a more significant control effect on the system error of each motor in comparison with the traditional relative coupling control structure.

“…Multi-motor synchronous control technology has been widely used in multi-axis servo systems. 1,2 The multi-motor synchronous control strategies mainly include master-slave synchronous control, adjacent coupling synchronous control, relative coupling synchronous control and virtual mainaxis synchronous control. [3][4][5] Zheng et al improved the master-slave synchronous control by compensating for the actuator's dead-zone effect and enhancing the synchronization performance of the 2-DOF master-slave manipulator.…”

A synchronous control system of virtual main-axis based on extended sliding mode disturbance observer is designed to solve some problems that coupling of multi-axis synchronous control of electronic gears is low and has poor anti-interference ability, and a large amount of synchronization error callback overshoot in bag-making machines. First, a velocity compensator is designed in order to establish the coupling relationship between the virtual and traction motor. Second, a nonsingular terminal sliding mode controller and a disturbance observer are used to enhance the anti-disturbance capability of the system. Finally, by using MATLAB/Simulink simulation, the viability and superiority of the method in multi-axis synchronous control are proved. The simulation results demonstrate that the control method decreases the synchronization error and the callback overshoot between the traction motors, and enhances the coupling performance and anti-interference ability of the system, which has a more significant impact on the high-performance synchronization control for the multi-traction motor system of the bag-making machine.
