Observer-Based Fault Estimation and Accomodation for Dynamic Systems

de Ke Zhang

<p>Due to the increasing security and reliability demand of actual industrial process</p><p>control systems, the study on fault diagnosis and fault tolerant control of dynamic</p><p>systems has received considerable attention. Fault accommodation (FA) is one of</p><p>effective methods that can be used to enhance system stability and reliability, so it</p><p>has been widely and in-depth investigated and become a hot topic in recent years.</p><p>Fault detection is used to monitor whether a fault occurs, which is the first step in</p><p>FA. On the basis of fault detection, fault estimation (FE) is utilized to determine</p><p>online the magnitude of the fault, which is a very important step because the additional</p><p>controller is designed using the fault estimate. Compared with fault detection,</p><p>the design difficulties of FE would increase a lot, so research on FE and accommodation</p><p>is very challenging. Although there have been advancements reported on FE</p><p>and accommodation for dynamic systems, the common methods at the present stage</p><p>have design difficulties, which limit applications of respective design approaches.</p><p>Therefore, the problems of FE and accommodation are needed to be further studied.</p><p>This book considers the theory and technology of FE and accommodation for</p><p>dynamic systems, and establishes a systemic and comprehensive framework of FE</p><p>and accommodation for continuous/discrete-time systems.</p><p> </p>
