“…The hybrid compliance's length l m is equal to 0.05m since it is the sum of two lengths: l m = l s + l a ; the length l s of the passive physical compliance, equal to 0.025 m, and the maximum displacement l a of the linear actuators' moving parts, equal to 0.025 m. The schematic of the system under simulation study as designed in Simscape is shown in Figure 15. The algorithm runs for the range of stiffness values k m between [0.1-0.5] N/m, with a step of 0.1 N/m, for a range of space debris mass m d between [1-100] kg, with a step of 1 kg, and for a range of minimum contact time t c required for completion of the capturing between [4][5][6][7][8][9][10][11][12] s, with steps of 2 s.…”

“…The resulting diagram is shown in Figure 16, providing the relation between these variables. More detailed visualization of the data of Figure 16 is provided for each contact time in the range of [4][5][6][7][8][9][10][11][12] s in Appendix A. The lines depicted in the 3D diagram correspond to points in 3D space, representing the successful cases obtained from the algorithm.…”

“…Each point along the line represents three distinct values, namely: space debris mass, minimum contact time achieved, and hybrid compliance stiffness coefficient. Note that the [4][5][6][7][8][9][10][11][12] s range for this simulation for the minimum contact time required was selected since it was sufficient to showcase the necessity of tuning the system's compliance and, therefore, of the hybrid compliance concept. Simulation results for minimum contact time required greater than 12 s show that hybrid compliance is even more necessary if we want to target a wide range of debris between 0-100 kg.…”

“…More detailed visualisation of the data of Figure 16 is provided for each contact time in the range of [4][5][6][7][8][9][10][11][12] s in Figures A1-A4 and 20. Based on the derived diagrams, the desired stiffness and damping coefficients of the hybrid system's equivalent compliance can be selected for a specific debris mass and minimum contact time required.…”

“…The problem with space debris is that most targets are not designed for removal. They are uncooperative for capturing [5] and they do not include specific grippers, handles, or markers to make capturing easier [6]. Additionally, each debris object has a unique geometry, velocity, and material [7].…”

Active debris removal (ADR) is positioned by space agencies as an in-orbit task of great importance for stabilizing the exponential growth of space debris. Most of the already developed capturing systems are designed for large specific cooperative satellites, which leads to expensive one-to-one solutions. This paper proposed a versatile hybrid-compliant mechanism to target a vast range of small uncooperative space debris in low Earth orbit (LEO), enabling a profitable one-to-many solution. The system is custom-built to fit into a CubeSat. It incorporates active (with linear actuators and impedance controller) and passive (with revolute joints) compliance to dissipate the impact energy, ensure sufficient contact time, and successfully help capture a broader range of space debris. A simulation study was conducted to evaluate and validate the necessity of integrating hybrid compliance into the ADR system. This study found the relationships among the debris mass, the system’s stiffness, and the contact time and provided the required data for tuning the impedance controller (IC) gains. This study also demonstrated the importance of hybrid compliance to guarantee the safe and reliable capture of a broader range of space debris.

This paper proposes an adaptive control scheme for capturing uncooperative space debris having uncertain inertial parameters. Debris parameters may be unknown or uncertain due to limited data or changes in orbit due to collisions. To address this challenge, the proposed scheme integrates an inertial parameter identification law with the impedance control strategy of FlexeS (Flexible Capture System). During the pre-capture phase, motion data is utilized to identify the debris' center of mass (CM), leading to the optimal capture point that minimizes impact moments. During contact, the impedance-controlled actuator(s) is(are) activated while the scheme concurrently provides accurate estimates of the debris mass and inertia, enabling the updating of controller gains and thus ensuring sufficient contact time for successful capture. Hence, the proposed adaptive scheme allows FlexeS to handle the debris parameter uncertainties. The simulation study demonstrates the scheme's effectiveness and necessity. The performance of the proposed adaptive scheme is compared with a non-adaptive scheme. The results affirm the superiority of the adaptive scheme in achieving successful soft capture of uncooperative debris in the presence of mass and inertia uncertainties and highlight its potential for future space debris mitigation missions.
