Integral Event Triggered Robust Attitude Stabilization for Flexible Spacecraft

In this work, an integral type event triggering strategy with fast terminal sliding mode convergence controller is proposed for attitude stabilization of spacecraft. The controller designed in sliding mode that can guarantee quick convergence to equilibrium states and saves communication resources. Also, the proposed controller aims to avoid unwinding problem in a unit quaternion-based attitude control. Simulation results shows integral event function minimize communication resources more than a linear event function.
