针对姿态跟踪控制问题，提出了一种新的具有通信节省能力的星内量化与基于事件的综合控制方案。IQEC方案基于基于事件的控制和量化通信技术，减少了控制更新频率和每次传输的数据长度，从而减少了系统通信占用。通过合适的控制系统配置，达到了从传感器到计算单元、从计算单元到执行器的通信节省的目的。通过采用具有二阶动力学的一般执行器模型的数值仿真，验证了所提算法的有效性。
A novel integrated quantized- and event-based control (IQEC) scheme for intra-spacecraft with communication-saving ability is proposed to address the attitude tracking control problem. The IQEC scheme reduces the control updating frequency and the data length per transmission based on the event-based control and quantized communication techniques, thus reducing the system communication occupation. By suitable control system configuration, the purpose of communication-saving is achieved, from sensors to the computing unit and from the computing unit to actuators. The proposed algorithm’s effectiveness is verified via numerical simulation that uses a general actuator model with second-order dynamics.
