Fuzzy anti-swing controller for improving handling quality of helicopter slung-load operation

In order to solve the problem of compromised flight quality in helicopter sling load operations—which arises from the trade-off between load stabilization and command responsiveness—this paper presented a unique fuzzy control solution that incorporates pilot intention. By developing a high-fidelity nonlinear model of the pilot-helicopter-slung-load system, this method tackles the inherent conflict between reducing load swing and maintaining precise control that is common in current anti-swing controllers. The proposed method can reasonably reflect the pilot’s intent, and a cable angle feedback control law has been demonstrated through simulation to dynamically adjust control parameters in line with pilot expectations. With good resilience, this integration reduces pilot-induced oscillations and conflicts between pilot actions and the control system.
