This article reports the design of a novel finite-time robust nonlinear controller for the synchronization of two identical chaotic spacecraft. The proposed controller does not cancel nonlinear terms appearing in the chaotic spacecraft dynamics. Avoiding the cancelation of the nonlinear terms of the plant by the controller makes the closed-loop robust stable in the presence of uncertainties in the chaotic spacecraft parameters; this concept blooms base for the design of computationally efficient simple control law. The proposed finite-time robust nonlinear controller (1) synchronizes two nearly identical chaotic spacecraft in finite-time duration, (2) expedites the convergence of errors vector to zero without oscillation, and (3) eradicates the effects of external disturbances. Analysis based on the Lyapunov second theorem proves that the synchronization error converges fast and verifying the closed-loop’s robust global stability. The finite-time stability technique affirms the convergence of the synchronization error to zero in settling time. This research article also studies the effects of the exogenous disturbances and the controller parameter’s slowly smooth variations on the closed-loop performance. The controller parameter variation analysis sets the procedure for tuning the controller parameters. The computer-based simulation results validate the theoretical findings and provide a comparative performance analysis with the other recently proposed synchronization feedback controllers. This article uses Mathematica 12.0 version in the Microsoft 10 environment for all the simulations.

“…In other words, the effectiveness of a synchronization algorithm is measured by its convergence time. Over the last decades, a variety of SFF attitude synchronization algorithms has been developed to satisfy SFF attitude synchronization requirements [1][2][3][4][5][6][7][8][9][10]. However, most existing results only show asymptotic convergence, which is slow and high-energy consuming.…”

This paper addresses the leader-follower finite-time attitude synchronization and stabilization for satellite formation flying (SFF) under directed switching communication topologies. Specifically, a distributed attitude synchronization control scheme is proposed to guarantee finite-time convergence to leader’s attitude and desired angular velocity for SFF under time-varying but jointly connected switching communication topologies. First, finite-time consensus protocols are designed for leader’s attitude tracking. The protocols are developed based on non-smooth control techniques such as homogeneity with dilatation and LaSalle invariance principle. Then, a distributed finite-time angular velocity estimator is designed using super-twisting sliding-mode control. The estimator helps solving communication loss issues, reducing communication burden, and canceling chattering effect due to high-rate convergence. Simulations are shown to illustrate the effectiveness of the obtained theoretical results.

“…In the existing literature, most of the 6-DOF SFF control designs assume a leader-follower architecture, such as [1,14]. This type of control is centralized, whereby increasing the number of followers, the leader controller structure becomes more complicated, and the loss of leader will result in mission failure [25]. In contrast, a decentralized controller is generated according to each follower's desired states, which is superior in terms of robustness and reliability [26].…”

“…In contrast, a decentralized controller is generated according to each follower's desired states, which is superior in terms of robustness and reliability [26]. The decentralized virtual structure method, where each follower's tracking errors are measured with respect to a virtual leader, has been used to solve the control problem of SFF involving a mass of spacecraft in [5,18,25]. For a 6-DOF SFF, besides the requirement of absolute attitude and position tracking, it also requires the followers to maintain relative attitudes and an accurate geometric configuration.…”
