Abstract: The attitude tracking control for spacecraft with limited communication and actuator faults is investigated in this paper by employing event-trigger-based prescribed control. Traditional methods struggle to address arbitrary initial conditions and fault-induced saturation, which both lead to prescribed control singularities, limiting practical deployment. This paper proposes the adhesive-resilient prescribed control (ARPC), which dynamically adjusts the performance envelope by sensing fault and error trends through resilient correction and an adhesive mechanism, respectively. This approach significantly enhances conservatism and robustness, particularly under actuator faults that exceed the saturation level. Additionally, the challenge of balancing high performance with low communication burden under limited resources is addressed. To mitigate communication frequency and bit consumption without sacrificing performance, a z -ary compression event-triggered scheme (CES) is introduced. Compared to existing methods, this work provides substantial improvements in fault tolerance, communication efficiency, and performance adaptability. Numerical experiments demonstrate the superiority of our method in regulating tracking error within a custom envelope and appointed time, regardless of initial conditions, while minimizing communication usage.
