Recently, with the trend of redundancy design, the importance of synchronous motion control of multiple motors has been emphasized in various fields such as automotive, construction, and industrial engineering. Therefore, this paper proposed a novel passive decomposition-based robust synchronous control strategy for a multi-motor system, guaranteeing that both the tracking error of each motor and the synchronous error between motors are ultimately and synchronously bounded, even under the presence of parametric uncertainty and unstructured external disturbance. Specifically, a passive decomposition is used to obtain the locked and shape systems from the original system, and then a sliding mode control system along with robust compensations is designed for each decomposed system to achieve the precise synchronous motion control of the n number of motors. Here, the controller for the locked system reduces the tracking errors of motors for a given desired trajectory, while the controller for the shaped system decreases the synchronous errors between motors. Furthermore, the control system is generally and conveniently formulated to adopt the arbitrary n number of motors that must track a given desired trajectory and be synchronized. Compared to other related studies, this work especially focused on increasing the robustness of the entire system using both high-order sliding mode control and two separate compensation terms for model uncertainty and unstructured external disturbance. Finally, to validate the effectiveness of the proposed synchronous control strategy, the extensive experimental studies on two/three/four-geared BLDC motors with a high dead-zone effect were conducted, and we also compared the synchronous control performance of the proposed control strategy with the other representative control approaches, a master–slave control scheme and an independent one to address the superiority of the proposed control system. Regardless of the number of motors, due to the robustness of the control system, it is found that the proposed control ensures the tracking and synchronous errors are less than 1 degree for the sine-wave trajectory while it guarantees that the errors are below 1.5 degree for the trapezoidal trajectory. This control approach can be widely and generally applied to the multiple motor control required in various engineering fields.

“…Additionally, research advancements on multi-phase machines may increase their use in vehicular applications [1]. Multiport and multi-phase motor drives are characterized with improved cost, size, reliability, and fault-tolerance abilities compared to a conventional solution of a separate drive for each motor [2], thus, making them an attractive solution for these applications.

This paper investigates and validates the applicability of the recently developed stray voltage capture (SVC) ultra-fast short-circuit (SC) detection method and its extended version (ESVC) to fault-tolerant multi-motor drives. As these methods are system-based, a fault localization algorithm is also developed. Simulation analysis of the inverter stray inductances shows additional challenges for the SVC method making it hard to achieve ultra-fast SC detection. The ESVC method is slower but overcomes these challenges. The methods are adapted for a 400 V 6-phase Silicon Carbide based inverter equipped with a 2-level turn-Off hardware protection scheme. Fault under load and hard switching fault tests are performed showing the effectiveness of the ESVC in fast (smaller than 330 ns) and reliable SC detection and protection for SiC MOSFETs. The fault localization algorithm is also validated showing a localization speed smaller than 20 µs.
