As the complexity of engineering systems is constantly increasing, their design calls for the sustainability and reliability of their high performance. Fault diagnosis (FD) is a vital system tool that addresses this critically-important issue. This book presents a clear and easy introduction to the sequential integration of the two major approaches to FD with application, namely model-free and model-based and draws on the power of the two approaches vitally for the detection of incipient faults which are hard to uncover by a single approach alone. In the model-free approach, this book...
