A Resilient Attitude Tracking Algorithm for Mechanical Systems

In this paper, we design an event-triggering based hybrid control strategy for the time-varying attitude tracking control of the aircraft system, where the networked communication is confined with denial-of-service (DoS) attacks. The designed control strategy introduces a binary-logic-variable-based hybrid control law to overcome the topological constraint on SO(3), together with an event-triggering sampling mechanism to determine when to update the designed controller. Combined with the two kinds of flows/jumps and a general explicit characterization of frequency/duration properties for DoS attacks, we establish a general hybrid formalism for the attitude tracking control. The designed event-based hybrid control scheme renders the globally asymptotic tracking control resilient to DoS attacks. Simulation results are presented to show the effectiveness of the established hybrid control strategy.
