In this article, we consider the attitude tracking control problem for rigid spacecraft with bounded external disturbances. We propose a predefined-time predefined-bounded scheme based on nonsingular sliding-mode manifold. The proposed controller is continuous and it can achieve stability. That is, errors are driven to region around origin within predefined time, which be set as tuning parameter during design, independently of initial conditions. Finally, numerical simulations carried out...
Abstract Large, 3D curved electronics are a trend of the microelectronic industry due to their unique ability conformally coexist with complex surfaces while retaining electronic functions 2D planar integrated circuit technologies. However, these present great challenges fabrication processes. Here, we propose reconfigurable, mask-free, conformal strategy robot-like system, called robotized ‘transfer-and-jet’ printing, assemble diverse devices on surfaces. This novel method is...
This article investigates the coupled attitude and orbit tracking maneuver control problem of a spacecraft system in close space missions with model uncertainty, unknown disturbance, input saturation. An adaptive compact scheme featuring disturbance rejection antiwindup is reported. First, exponential coordinates on Lie group SE(3) are employed to describe relative pose, which includes position attitude, error established by introducing an instrumental variable, contains velocity error....
While there is ample research on hardware design and reconfiguration control for modular self-reconfigurable satellites, relatively few planning algorithms, especially algorithms used in real-world have been developed. Decentralized path planning, which only uses partial observation each module to make decision an important problem task. This article presents partially observable self-reconfiguration addressing the a single using observations while aiming maximize policy learning efficiency....
This paper is concerned with the problem of robust filter design for a class discrete-time networked nonlinear systems. The Takagi-Sugeno fuzzy model employed to represent underlying dynamics. A multi-channel communication scheme that involves channel switching phenomenon described by Markov chain proposed data transmission. Two typical imperfections, network-induced time-varying delays and packet dropouts are considered in each channel. objective this an admissible such error system...
This article addresses the coupled orbit-attitude tracking problem using low-thrust propulsion while aiming to minimize on-board spacecraft system communication. An adaptive controller is proposed by employing an event-triggered control and extended-state-observer, where a simple strategy tune observer parameters provided. Moreover, event-triggering updates allocates signal thrusters at prescribed discrete events shown significantly reduce data-rate requirement. Finally, performance of...
Fault-tolerant attitude tracking control for rigid-flexible coupled spacecraft is studied in this article. Taking actuator faults, measurement errors of and angular velocity, unmeasured modal displacements, model uncertainties, external disturbances into consideration, an adaptive fault-tolerant designed. Then, based on the sequential Lyapunov method, stability closed-loop system analyzed showing that if velocity are bounded, then successively less conservative bounds error can be obtained.
This article addresses the velocity-free attitude control problem for rigid spacecraft with bounded external disturbances. To obtain an accurate estimate of spacecraft's velocities and disturbances, a semiglobal practical predefined-time extended-state observer is presented in terms time-dependent scaling function. Next, continuous nonsingular sliding mode surface designed, introduced to derivative term surface. Then, scheme proposed spacecraft. The developed controller can ensure that upper...
In this paper, attitude coordination control for flexible spacecraft formation flying (SFF) is investigated in the condition that common reference only available to a subset of followers group. Measurement errors, immeasurable modal variables, external disturbances and model uncertainties both rigid dynamics are addressed concurrently. Then based on sequential Lyapunov method, successively less conservative performance bounds can be obtained with proposed distributed controller.
