Abstract
Reusable launch vehicles (RLVs) offer advantages such as low cost and high efficiency, yet they still face challenges related to real-time precise control and reliability enhancement. To address these issues, this paper presents a fixed-time attitude control method designed for RLVs, incorporating a reliability-based control allocation scheme. Initially, a fixed-time radial basis function neural network (RBFNN) disturbance observer is introduced to estimate disturbances rapidly and accurately. Subsequently, a control method integrating non-singular terminal sliding mode control (NTSMC) with a saturation compensator is proposed to achieve real-time and precise angle tracking. Furthermore, a reliability-based control allocation scheme is employed to enhance the reliability of the attitude control system. Finally, simulation analysis is conducted to validate the effectiveness of the proposed control scheme.
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.
