Flight Control Failure Detection and Control Redistribution Using Multiple Model Adaptive Estimation with Filter Spawning
Abstract
In the current research, the MMAE with Filter Spawning and Control Redistribution (MMAE/FS/CR) are used together to identify failures and apply appropriate corrections. This effort explores the performance of the MMAE/FS/CR in different regions of the flight envelope using model and gain scheduling. The MMAE/FS/CR is able to detect complete and partial actuator/surface failures, as well as complete sensor failures. Once the actuator/surface failure is identified and the effectiveness is determined in the case of partial failures, proper control is applied in order to accomplish the desired pilot command. Improvements in the algorithm are required in order to enhance the MMAE/FS/CR ability to detect failures while undergoing maneuvering flight. This investigation shows the ability of the MMAE/FS to detect failures while transitioning through the flight envelope and while performing pilot commanded maneuvers. It also improves and demonstrates the CR ability to compensate for complete or partial actuator/surface failures.
