Reliability, safety, and availability (RSA) are broad, integrated and definitely core issues in human life. There are wide varieties of systems that their RSA are so critical to our lives. Electrical grids (from power generation to distribution), transportation systems (manned and unmanned aerial/ground/surface vehicles (UAVs/UGVs/USVs), etc.) are important examples of these safety-critical systems. One important question is that how reliable and resilient is our today's grid? The RSA of the power systems are being challenged, as the infrastructure ages and as new operating challenges emergeincluding the generation and integration of intermittent renewable energies like wind and solar. To address such challenges, the next-generation electricity grid, known as smart grid, will be a network of integrated microgrids that are geographically compact units capable of integrating local renewable energy generation. For such an interconnected network, the relevant components and units need to be controlled in a cooperative framework capable of providing power that is reliable, efficient, and environmentally responsible. In the other examples of safety-critical systems such as UAVs/UGVs/USVs, the necessity of RSA is even more immediate. From TV news, we hear about some natural disasters such as earthquakes, volcanoes, forest fires, and nuclear reactor malfunctions. For these dangerous and uncertain environments, it is difficult or unsafe to deal with these disasters by personnel and manned systems. Therefore, unmanned systems (USs), including UAVs, UGVs and USVs, become useful and more and more popular. With the aid of a group of USs, we can complete certain difficult missions which cannot be completed with a single vehicle and impossible before. In this case, fault-tolerant cooperative control (FTCC) among the group of USs becomes necessary for practical applications since one or more USs may fail to operate during a mission due to possible system malfunctions, damages, communication failures. Considering the above-mentioned facts, one question arises naturally: how to guarantee the RSA requirements of the above-mentioned safety-critical systems? In fact, the most enabling technologies to guarantee the mentioned requirements include effective techniques for monitoring, fault diagnosis, and FTCC. Although the mentioned safety-critical systems belong to different disciplines ranging from aerospace, mechanical, and electrical systems, they are similar from control and condition monitoring viewpoint. The objective of this proposal is to develop advanced and practical techniques for providing possible solutions to the above-mentioned issues and applications with systematic theory and methodologies. In another words, the main task of this project is to develop new fault diagnosis and FTCC techniques to USs and smart grids in such cutting-edge research and development areas.

可靠性、安全性和可用性 (RSA) 是人类生活中广泛、综合且绝对的核心问题。系统种类繁多，其 RSA 对我们的生活至关重要。电网（从发电到配电）、交通系统（有人和无人驾驶航空/地面/水面车辆（UAV/UGV/USV）等）是这些安全关键系统的重要示例。 一个重要的问题是，我们今天的电网的可靠性和弹性如何？随着基础设施老化和新的运营挑战（包括风能和太阳能等间歇性可再生能源的发电和整合）的出现，电力系统的 RSA 正面临挑战。为了应对这些挑战，下一代电网（称为智能电网）将是一个集成微电网网络，这些微电网是地理上紧凑的单元，能够整合当地可再生能源发电。对于这样一个互连的网络，相关组件和单元需要在一个能够提供可靠、高效且对环境负责的电力的合作框架中进行控制。 在 UAV/UGV/USV 等安全关键系统的其他示例中，RSA 的必要性更加迫切。从电视新闻中，我们听到一些自然灾害，如地震、火山、森林火灾、核反应堆故障等。对于这些危险和不确定的环境，人员和载人系统应对这些灾难是困难或不安全的。因此，包括UAV、UGV和USV在内的无人系统（US）变得有用且越来越受欢迎。在美军的帮助下，我们可以完成一些单车无法完成、以前不可能完成的困难任务。在这种情况下，一组US之间的容错协作控制（FTCC）对于实际应用来说变得必要，因为一个或多个US在任务期间可能由于可能的系统故障、损坏、通信故障而无法运行。 考虑到上述事实，自然而然地出现了一个问题：如何保证上述安全关键系统的RSA要求？事实上，最能保证上述要求的技术包括有效的监控技术、故障诊断技术和FTCC技术。尽管上述安全关键系统属于航空航天、机械和电气系统等不同学科，但从控制和状态监测的角度来看，它们是相似的。本提案的目的是开发先进实用的技术，通过系统的理论和方法为上述问题和应用提供可能的解决方案。换句话说，该项目的主要任务是为美国和智能电网等前沿研发领域开发新的故障诊断和FTCC技术。
