Aiming at the principles of determining testability interface signal, methods and procedures, and the paper puts forward the conception of equipment testability interface and testability interface signal. This will lay a foundation for the systemic studies of laws of change of each key component status of equipment and fault diagnosis as well as offer the theoretical basis and references for the research...
Dedicated Observer Scheme (DOS) was used for fault detection and isolation which adopted EMB (electro-mechanical braking) system. Base on the mechanical model of EMB, two independent Kalman filters were designed for the fault detection of EMB sensors. Computer simulation showed that DOS has made a good use at fault isolation and detection for EMB sensors, and it also had high real-time property.
The problem of integrated fault diagnostic and fault-tolerant control for uncertainty linear system is developed. Focusing on the actuator and sensor faults of satellite, we presents a fault diagnosis method based on sliding mode observer. And considering the uncertainties of diagnosis results, we also design a Hinfin state-feedback controller to achieve the fault-tolerance by solving a linear matrix...
