Wind gusts are among the well-known disturbances that afflict aerial systems. A tracking task for a load suspended by massless rigid bars and quadrotors is considered in this paper. The complexity of the tracking task lies in the presence of wind gusts. Therefore, a self-tuning gain technique for a proportional-integral-derivative (PID) control is introduced to accomplish tracking tasks when wind gusts appear. To automatically tune the PID gains, a sliding mode condition is exploited. The stability of this approach, considering bounded disturbances, is guaranteed by introducing a supervisory control designed through the Lyapunov method. The proposed solution and its performances were tested through simulation and compared with both PD and PID controls.

Abstract
Wind gusts are among the well-known disturbances that afflict aerial systems. A tracking task for a load suspended by massless rigid bars and quadrotors is considered in this paper. The complexity of the tracking task lies in the presence of wind gusts. Therefore, a self-tuning gain technique for a proportional-integral-derivative (PID) control is introduced to accomplish tracking tasks when wind gusts appear. To automatically tune the PID gains, a sliding mode condition is exploited. The stability of this approach, considering bounded disturbances, is guaranteed by introducing a supervisory control designed through the Lyapunov method. The proposed solution and its performances were tested through simulation and compared with both PD and PID controls.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
