“…Considered the best approach for speed synchronization of motors, the virtual line-shafting control stems from a concept by Lorenz and Schmidt, who developed a motor synchronization method based on relative stiffness control [13]. Afterwards, this idea evolved into the virtual lineshafting method ( [14], [15], [16], [17]) where this concept is applied to industrial applications where coordination was crucial, such as paper machines, winding machines, etc.…”

Electromechanical actuators (EMAs) begin to have a greater presence in current aeronautic designs due to the energy efficiency and reliability advantages they can provide. However, the conventional mechanical design with a single combination of a ball screw and an electric motor is subject to scenarios in which a single point of failure can render it inoperative. This paper presents a failsafe innovative EMA that gives a solution to the most typical jamming issues of aeronautical electromechanical actuators, either due to ball screw or electric motor failures. Different electric motor synchronization techniques applicable to the presented mechanical EMA design are analysed, and the benefits of the most adequate control strategy, the virtual line-shafting (VLS), are validated. Finally, the implementation of the control algorithm in a simplified virtual test bench with promising results is shown. The obtained results demonstrate that the proposed novel EMA mechanical design can enhance the failsafe capabilities of the current EMA designs based on a single ball screw and motor combination.

“…The main types of coupling control are virtual spindle control [8], cross-coupling control [9], and deviation coupling control [10]. Virtual spindle control makes the multi-motor system keep synchronization by simulating the motion characteristics of the mechanical total axis [11].…”

Aiming at the problems of uneven parameter differences and load torque distribution, which cause the tracking accuracy and synchronization performance of the multi-motor control system to be reduced, a multi-motor system control strategy with sliding mode virtual spindle adjacent cross-coupling control is proposed. First, the feedback torque of each motor is regulated by establishing a virtual spindle to improve the coordination of the system. Secondly, a speed compensator is designed to couple each motor to improve the system synchronization. Meanwhile, the sliding mode control strategy is used for the control of a single motor. The robustness and tracking accuracy of the system are tuned up. The simulation experiment results show that compared with the sliding mode cross-coupling control, sliding mode adjacent deviation coupling control, and PI virtual spindle-adjacent deviation coupling control, the system has a small synchronization error, strong anti-interference ability, and realizes high-precision coordinated control of multiple motors.

“…Where, the Non-coupling control includes master command control, master-slave control, and virtual axis control. Literatures 10,11 is using master-slave control, and this scheme also has the problem of large-signal transmission delay; However, in literatures 12,13 proposed virtual axis control, which realizes the synchronous control of multiple motors, but this control strategy has some problems such as given signal delay. Coupling control includes cross-coupling, adjacent coupling, deviation coupling, etc.…”

Multi-motor synchronous drive system is increasingly widely used in industry and manufacturing, where its control structure and control strategy affect the quality and efficiency of production. In order to solve the contradiction between fastness and overshoot, and the difficulty in determining the compensation law in the conventional PID, cross-coupling control, and master-slave control strategies used in multi-motor control, this paper proposes a self-coupling PID control strategy based on ring adjacent compensation to reduce the complexity of the control structure. Furthermore, this paper analyzes the self-coupling PID parameter tuning rules and establishes the control structure of the ring coupling strategy, and proves its validity mathematically. The simulation results verify that the proposed strategy provides a fast response speed, high control precision, good disturbance rejection, and synchronization performance.
