Introduction

Abstract

Modern technological devices rely on sophisticated control systems to meet increased performance requirements. For such systems, the consequences of faults in system components can be catastrophic. Reliability of such systems can be increased by ensuring that faults will not occur, however, this objective is unrealistic and often unattainable because faults may arise not only due to components aging and wear, but also as human errors in connection with installation and maintenance. Therefore, it is necessary to design control systems that are able to tolerate possible faults in such systems to improve reliability and availability. This type of control systems is often known as Fault Tolerant Control Systems (FTCSs), which can be classified into two categories: active and passive. In this book, we are concerned with the design and analysis of active FTCSs.
