For aircraft control engineers, it reveals a previously overlooked nonlinear dynamic phenomenon that can cause instability in saturated control systems.
The paper demonstrates the existence of hidden oscillations (attractors) in aircraft control systems with magnitude and rate saturation, using examples of pilot-induced oscillations and airfoil flutter suppression.
In the paper, the control problem with limitations on the magnitude and rate of the control action in aircraft control systems, is studied. Existence of hidden oscillations in the case of actuator position and rate limitations is demonstrated by the examples of piloted aircraft pilot involved oscillations (PIO) phenomenon and the airfoil flutter suppression system.
