Abstract Plug-and-play modular design is the future of spacecraft manufacturing. The employment of wireless communication between different modules instead of wire connections can reduce weight and simplify assembly. This paper focuses on the design of spacecraft attitude tracking control policies under wireless communications. A new event-based control policy with performance adjustable functions is proposed to achieve intermittent sampling to save system resources. Under the designed policy, the sampling frequency and convergence rate of the considered system can be traded off by designing different performance adjustable functions. Based on the Lyapunov function method, it proves that the spacecraft attitude tracking errors are uniformly ultimately bounded. In comparison with the previous results, the proposed policy provides a more general triggering condition and has the property of freely adjustable performance, which is suitable for scenarios with different performance requirements. Numerical simulations support the conclusion of its effectiveness and superiority.
