A Method for PIO Suppression in Aircraft with Fly-By-Wire Controls: System Development and Validation via Flight Simulator Tests
This article introduces a technique for suppressing pilot-induced oscillations (PIO) in aircraft equipped with fly-by-wire (FBW) flight controls. Drawing from the real-time oscillation verifier (ROVER) concept proposed by Mitchell and Hoh, in 1994, and an adaptive suppression system by Moura in 201...

This article introduces a technique for suppressing pilot-induced oscillations (PIO) in aircraft equipped with fly-by-wire (FBW) flight controls. Drawing from the real-time oscillation verifier (ROVER) concept proposed by Mitchell and Hoh, in 1994, and an adaptive suppression system by Moura in 2018, the method involves dynamically adjusting stability derivatives via software during aircraft operation. The ROVER detects PIO conditions during flight, directing changes to the aircraft’s dynamics. Switching to a less susceptible model during PIO mitigates oscillations. The study focuses exclusively on longitudinal motion and pitch angle control. The proposed system is implemented and simulated using MATLAB routines, complemented by human pilot trials on a flight simulator. Results demonstrate real-time detection of PIO oscillations and effective mitigation, ensuring system integrity with acceptable degradation in flight qualities during transitions.
