G. Ducard, H. P. Geering, “SMAC-FDI: New Active Fault Detection and Isolation Scheme with High Computational Efficiency," Proceedings of the 2010 Conference on Control and Fault-Tolerant Systems (SysTol'10), pp. 30-37, Nice, France, October 2010.

This paper presents a new scheme for actuator fault detection and isolation (FDI) with application to actuator health monitoring on an aircraft. The Single Model Active Fault Detection and Isolation System (SMAC-FDI) efficiently detects and isolates a faulty actuator in a system. This method has a short response time and is robust against model uncertainties, sensor noise, external disturbances. The algorithm is computationally efficient. No sensor is needed to measure the position of an actuator. The method is illustrated on an small unmanned aircraft.
