Isolation and handling of actuator faults in nonlinear systems. (English)
[J] Automatica 44, No. 1, 53-62 (2008). ISSN 0005-1098

Summary: This work considers the problem of control actuator fault detection and isolation and fault-tolerant control for a multi-input multi-output nonlinear system subject to constraints on the manipulated inputs and proposes a fault detection and isolation filter and controller reconfiguration design. The implementation of the fault detection and isolation filters and reconfiguration strategy are demonstrated via a chemical process example.
