Presidential Young Investigator Award: Fault Tolerant Design of Electromechanical Systems

这项研究的目的是研究机电系统的集成设计，特别考虑预防性维护、自动故障诊断、容错操作和改进的可维护性。该方法包括利用工厂模型中存在的分析冗余，而不是更昂贵的硬件冗余解决方案。这种强调系统建模、故障模式和影响分析、控制系统设计和诊断集成的设计方法的潜在应用领域很多，从重型工业机械到精密机电运动控制设备。将考虑将该设计方法具体应用于以集成电路形式实现其硬件的机电系统。产业协作将为这项研究的原型开发部分提供试验台。

The objective of this research effort is to investigate the integrated design of electromechanical systems with specific consideration of preventive maintenance, automated failure diagnosis, fault tolerant operation and improved serviceability. The approach consists of exploiting the analytical redundancy present in models of the plant over more costly hardware redundancy solutions. Potential areas of application for such a design methodology which emphasizes the integration of system modelling, failure mode and effects analysis, control system design, and diagnostics are many, ranging from heavy industrial machinery to precision electromechanical motion control devices. A specific application of the design methodology to an electromechanical system, with its hardware realization in integrated circuit form, will be considered. Industrial collaboration will provide both the testbed for the prototype development segment of this research effort.
