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 emerge—including 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）在人类生活中是广泛，综合且绝对是核心问题。系统的RSA对我们的生活至关重要。电网格（从发电到分销），运输系统（载人和无人驾驶/地面/地面车辆（无人机/ugvs/usvs等））是这些安全 - 关键系统系统的重要例子。随着基础设施的年龄和新的操作挑战，电力系统的RSA受到挑战，包括诸如风能和太阳能等间歇性可再生能源发电的产生和整合。为了应对此类挑战，下一代电网（称为智能电网）将是一个集成的微电网网络，这些网络是能够整合本地可再生能源产生的地理紧凑型单元。对于这样一个相互联系的网络，相关组件和单位需要在能够提供可靠，高效且对环境负责的权力的合作框架中进行控制。 ***在其他至关重要的系统（例如UAVS/UGVS/USV）的其他示例中，RSA的必要条件更加直接。从电视新闻中，我们听到了一些自然灾害，例如地震，火山，森林大火和核反应堆故障。对于这些危险和不确定的环境，很难或不安全地应对人员和载人系统来应对这些灾难。因此，包括无人机，UGV和USV在内的无人系统（USS）变得有用，越来越受欢迎。借助一组US，我们可以完成某些难以用一辆车辆完成的困难任务，而以前不可能完成。在这种情况下，对于实际应用，在USS组中具有耐断层的合作控制（FTCC）是必要的，因为一个或多个US可能由于可能的系统故障，损害，沟通失败而在任务中无法运行。实际上，保证上述要求的最有能力的技术包括用于监视，故障诊断和FTCC的有效技术。尽管上述安全 - 关键系统属于从航空航天，机械和电气系统等不同学科，但从控制和状况监测的角度来看，它们相似。该提案的目的是开发先进和实用的技术，以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。另外，该项目的主要任务是在此类尖端的研究和开发领域为US和智能电网开发新的故障诊断和FTCC技术。
