Aerospace power systems provide the thrust of forward movement and the necessary speed to lift off for aircrafts. The most important part in an aerospace power system is the aircraft engine. With the development of science and technology in various countries, people have higher and higher requirements on the control performance of aerospace power systems,which undoubtedly increases the control difficulty of aerospace power systems.
Sliding mode theory includes sliding mode controller design method and sliding mode observer design method. Because of the good robustness and relatively simple strategy,sliding mode theory has attracted more and more attentions all around world from science researchers to engineering technicians.
The control systems in modern aircraft engines are carried out by Full Authority Digital Electronic Control (FADEC) systems. The FADEC needs to work with the signal measured by the relevant sensors on the aircraft engine, which contains a large number of electronic components, sensors and actuators. Most of these components work in the working environment of high temperature, high pressure and alternating stress of aircraft engine, which makes them prone to failure and several faults occur frequently. Once serious faults occur, the consequence may be unimaginable. Therefore, fault diagnosis and fault tolerant control for aerospace power system is particularly important.
In view of this, we write this book by summarizing years of scientific research results,focusing on the sliding mode theory for the fault diagnosis and fault tolerant control of aerospace power systems.
Focussing on the fault diagnosis and fault tolerant control problems in aerospace power systems, this book introduces a variety of sliding mode observer design, sliding mode controller design and sliding mode fault tolerant control system construction methods.Correspondingly, except the Chapter 1, which is the introduction, there are three parts in this book. The first part includes six chapters, which discuss fault diagnosis of aerospace power systems. The second part includes five chapters and different sliding mode control methods are presented for aerospace power systems. The third part, which is comprised of seven chapters, shows several fault tolerant control methods for aerospace power systems.
We sincerely thank our students and friends. Thank you for your help and support in writing this book.
In the process of editing and publishing this book, many staff in Beihang University Press have worked hard, and we would like to express our gratitude here also.
Limited to our ability, this book is inevitably inadequate or even wrong, and we urge readers, experts and scholars from all areas to criticize and correct us.
