When targeting mission critical applications, the design of the electronic actuation systems needs to consider many requirements and constraints not typical in standard industrial applications. One of these is tolerance to faults, as the unplanned shutdown of a critical subsystem, if not handled correctly, could lead to financial harm, environmental disaster, or even loss of life. One way this can be avoided is through the design of an electric drive systems based on multi-phase machines that can keep operating, albeit with degraded performance, in a partial configuration under fault conditions. Distributed architectures are uniquely suited to meet these challenges, by providing a large degree of isolation between the various components. This paper presents a system architecture suitable for scalable and high-performance fault tolerant machine drive systems. the effectiveness of this system is demonstrated through theoretical analysis and experimental verification on a six-phase machine.

用于高性能容错机器驱动器的可扩展系统架构

当以关键任务应用为目标时,电子驱动系统的设计需要考虑许多标准工业应用中不常见的要求和约束。其中之一是容错能力,因为关键子系统的意外关闭,如果处理不当,可能会导致经济损失、环境灾难甚至生命损失。可以避免这种情况的一种方法是通过设计基于多相电机的电驱动系统,该系统可以在故障条件下的部分配置中保持运行,尽管性能下降。通过在各种组件之间提供高度隔离,分布式架构非常适合应对这些挑战。本文提出了一种适用于可扩展和高性能容错机器驱动系统的系统架构。通过在六相电机上进行理论分析和实验验证,证明了该系统的有效性。
