Forthcoming articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

  • Event-Triggered based Actuator Failure Compensation for Flexible Manipulators   Order a copy of this article
    by Shengjie Xing, Dong Zhao, Darong Huang 
    Abstract: Aiming at the problem of fault compensation of flexible single-link manipulator system, this paper proposes an adaptive boundary fault-tolerant control scheme based on event triggering. Firstly, a static event-triggered mechanism is constructed to decrease the consumption of input signal resources. Then, due to the improved Lyapunov method, the adaptive boundary fault-tolerant control rate and parameter updating rate are designed to ensure that the flexible single-link manipulator system can achieve posture tracking and suppress vibration in the case of actuator failure. Finally, the numerical simulation verify the validity of the proposed adaptive fault-tolerant control algorithm.
    Keywords: Adaptive Control; Boundary Control; Event-triggered Mechanism; Flexible Manipulator; Actuator Fault.

  • H_infty Almost Distributed Voltage Control for DC Microgrid: a PD-Like Design Approach   Order a copy of this article
    by Jinzhou Yang, Zhenwei Liu 
    Abstract: This paper focuses on the distributed voltage control problem of DC microgrids consisting of some different types of DC distributed generation (DG) units powered by wind and solar energies. A distributed voltage controller is developed for this DC microgrid to make all DG's voltages synchronise to a reference voltage. Meanwhile, the controller is designed by using a distributed PD idea, and based on multi-agent system (MAS) with external disturbances which is obtained by transforming the original microgrid model. Finally, the simulation results show the effectiveness of the proposed approach.
    Keywords: DC microgrid; distributed voltage control; PD-like controller; H_infty almost.

  • Nested Signal Temporal Logic Specifications of Nonlinear Systems via Time-Varying High Order Control Barrier Functions   Order a copy of this article
    by Shenyang Wang, Yazhou Wang, Lijun Long 
    Abstract: This paper addresses a control synthesis problem for a class of nonlinear systems with disturbances under nested signal temporal logic (STL) specifications. While most existing literature on control synthesis using control barrier functions (CBFs) to satisfy STL specifications does not address nested temporal operators and often assumes nominal (disturbance-free) systems, we propose a control framework based on STL incremental (STLInc), disturbance observers (DOBs), and time-varying high-order control barrier functions (HOCBFs) to address these gaps. Specifically, the proposed control framework uses STLInc, an incremental planning framework, to decompose nested STL formulas into a series of sub-specifications through two steps: flattening and scheduling. Then, control strategies are synthesized by using DOBs and time-varying HOCBFs to satisfy these sub-specifications. Also, the nested STL specifications are satisfied even when the system is disturbed. Finally, a 2D robot navigation example is presented to demonstrate the effectiveness of the proposed control framework.

  • Real-time Detector on SMT Chip Component Defect Detection   Order a copy of this article
    by Wangyou Gui, Zhenyi Xu, Yunbo Zhao, Lijun Zhao 
    Abstract: Defect detection in surface mount technology (SMT) is critical for electronics quality control. Traditional automated optical inspection (AOI) faces slow speed and high misdetection, while existing deep learning methods trade accuracy (one-stage) for real-time performance (two-stage). We propose SMT DETR, a lightweight real-time algorithm for SMT defect detection. First, an adaptive collaborative feature extraction module (ACBlock) enhances sensitivity to component deformations and defects. Second, a novel IMIoU loss improves tiny object detection and accelerates convergence by optimising IoU computation. We also construct the SMT chip component dataset (SMTC). Experiments show SMT-DETR outperforms state-of-the-art methods on SMTC and achieves competitive results on public datasets, balancing accuracy and real-time efficiency for industrial applications.
    Keywords: SMT defect detection; DETR; IMIoU Loss.
