Bell V-280 System Identification: Application of JIO Methodology for Hover Model Identification

With modern advanced aerospace vehicle configurations, highly coupled redundant flight control surfaces are becoming standard practice. For such vehicles, traditional System Identification (SID) methods, may not accurately capture the individual contributions of effectors to the vehicle bare-airframe response. For the Bell V-280 in a hover configuration, this work used standard SID and the Joint Input-Output (JIO) method to obtain the control power of highly correlated control effectors. The methodology was demonstrated using a high-fidelity hardware-in-the-loop simulation in the V-280 System Integration Lab (SIL), where the identification results can be compared with the known simulation model.
