Reliable Fault tolerant system design based on Dynamic safety margin
Dynamic safety margin (DSM) is a new performance index used to measure the distance between a predefined safety boundary in the state space and the system trajectory as it evolves. Controller design based on DSM is important to maintain a predefined margin of safety during the transient and in the pres┬Čence of large disturbances particularly in safety-critical sys┬Čtems. Moreover, Designing a Fault Tolerant Control (FTC) system based on DSM is important to operate the system at an acceptable performance in addition to maintain a safe operation margin during the fault period. Some methods of implement DSM in controller design and adaptation are introduced in this work mainly, PID and MPC controllers. Moreover, a framework of FTC sys-tem based on DSM is introduced
