“…The overall definition of the coordinate system of the cableless non-contact close-proximity formation satellite is shown in Figure 2. According to the architecture shown in Figures 1 and 2, the dynamics are given in terms of a quaternion as follows, based on our previous research [10,32]:…”

“…According to the dynamics shown in Equations ( 1)-( 6), the PM can be considered as a rigid body. In this non-contact architecture, unprecedented attitude control accuracy and stability can be achieved using ADRC or LFPD control; its feasibility has been demonstrated in our previous research [10,32]. From the perspective of engineering application, we design actived attitude control law for the PM based on the conventional time-triggered LFPD control as follows:…”

“…Lockheed Martin built a single rotation degree-offreedom and two translation degree-of-freedom system based on planar air-bearing to verify the concept of a non-contact satellite platform [7], but it was not sufficient to verify the control problem under multi-dynamic coupling. In recent years, linear feedback proportion differentiation (LFPD) control [8], twistor-based synchronous control [9], and active disturbance rejection control (ADRC) [10] based on Newton Euler modeling approaches have been used to solve the multi-body dynamics coupling control problem. Meanwhile, advanced control methods such as optimal control, fuzzy control and deep reinforcement learning have been successfully applied in various complex nonlinear control systems, which can provide effective solutions for spacecraft control [11][12][13].…”

The cablelessness of non-contact close-proximity formation satellites can fundamentally avoid the influence of non-contact interface coupling effects and can further enhance the attitude pointing accuracy and stability of the payload module (PM). However, it also brings the problem of limited on-board resources and system latency. In this paper, an event-triggered attitude tracking controller of the support module (SM) that avoids the Zeno phenomenon was proposed. The update time of the control signal was determined by the event-triggering mechanism based on intermediate variables, thus, reducing the communication burden and actuator asynchrony between the two modules. The feasibility and effectiveness of the proposed approach was demonstrated by numerical simulations.

The CHASE satellite is designed based on the novel ultra-high pointing accuracy and stability levitated-body satellite platform, which breaks the traditional idea of rigidly connecting the satellite platform and payload. When operating in orbit, the platform and payload are non-connected and spatially levitated. By separately arranging the "noisy" and "quiet" devices, the complicated influence of platform vibration on the payload pointing direction is effectively avoided. Using the novel master-slave collaborative control method, the pointing accuracy and stability of the payload are improved considerably. In this paper, the basic principles, overall scheme, control method, and engineering implementation of a levitated-body satellite platform are discussed. Combined with the CHASE mission in-orbit data, the actual attitude pointing precision and stability of a levitated-body satellite platform are analyzed and evaluated.
