This study investigates the problem of attitude control design for spacecraft operating in a bandwidth-restricted environment. The proposed control solution should ensure robustness toward unknown inertia and disturbance-induced uncertainties in tandem with an economically efficient utilization of network resources. The study is conducted is to develop an attitude controller that stabilizes the states of the spacecraft while avoiding unwinding problem. It also needs to provide robustness toward unknown uncertainties and disturbances with minimum use of communication resources. A comparative numerical analysis of the proposed strategy with a newly developed event triggered (ET) sliding mode control (SMC) scheme is also presented.
