The relationships between control allocation and PIO susceptibility are analyzed. The PIO susceptibility of an example aircraft with multiple control effectors (MCE) in 3 different control allocation schemes is evaluated by time domain Neal-Smith criterion. The results indicate that control allocation obviously influence the PIO susceptibility of aircrafts with MCE.
