Abstract

This article presents a robust adaptive control approach for achieving high-precision attitude control in spacecraft pointing applications. The proposed strategy ensures reference attitude tracking within a predefined time, despite initial state variation and practical challenges such as parametric uncertainties, unknown disturbances, time-varying inertia, actuator saturation, and faults. Additionally, the attitude pointing errors are guaranteed to meet prescribed performance bounds in both transient and steady-state accuracy. This is achieved by constraining the pointing errors to follow a novel predefined time prescribed performance function (PT-PPF), designed in advance to satisfy pointing requirements. The time-varying attitude constraints are enforced using a barrier Lyapunov function (BLF)-based control law, synthesized through the backstepping and dynamic surface control technique. Stability of the proposed controller is rigorously analyzed using Lyapunov theory. The effectiveness of the control law is demonstrated in a high-precision Sun-pointing scenario for a spacecraft in a Sun–Earth

期刊介绍： Control Engineering Practice strives to meet the needs of industrial practitioners and industrially related academics and researchers. It publishes papers which illustrate the direct application of control theory and its supporting tools in all possible areas of automation. As a result, the journal only contains papers which can be considered to have made significant contributions to the application of advanced control techniques. It is normally expected that practical results should be included, but where simulation only studies are available, it is necessary to demonstrate that the simulation model is representative of a genuine application. Strictly theoretical papers will find a more appropriate home in Control Engineering Practice''s sister publication, Automatica. It is also expected that papers are innovative with respect to the state of the art and are sufficiently detailed for a reader to be able to duplicate the main results of the paper (supplementary material, including datasets, tables, code and any relevant interactive material can be made available and downloaded from the website). The benefits of the presented methods must be made very clear and the new techniques must be compared and contrasted with results obtained using existing methods. Moreover, a thorough analysis of failures that may happen in the design process and implementation can also be part of the paper. The scope of Control Engineering Practice matches the activities of IFAC. Papers demonstrating the contribution of automation and control in improving the performance, quality, productivity, sustainability, resource and energy efficiency, and the manageability of systems and processes for the benefit of mankind and are relevant to industrial practitioners are most welcome.
