DOI: 10.1002/rnc.70304

Abstract: The predefined‐time nonsingular fast terminal sliding mode (NFTSM) control problem is studied based on a prescribed‐time disturbance observer (PTDO) for a robotic manipulator system with Denial‐of‐Service (DoS) attack. Firstly, a new predefined‐time NFTSM control strategy… read more here.

DOI: 10.1002/rnc.7356

Abstract: This article proposes a finite time disturbance observer (FTDO) with modified non‐singular terminal sliding mode control (NTSMC) scheme for permanent magnet synchronous motor with unknown uncertainties such as system uncertainties and disturbances. A FTDO is… read more here.

DOI: 10.1007/s10344-018-1217-7

Abstract: Some protected species have benefited from human activities to a point where they sometimes raise concerns. However, gaps in knowledge about their human-related behaviour hamper effective management decisions. We studied non-breeding common ravens Corvus corax… read more here.

DOI: 10.1109/taes.2025.3578288

Abstract: This article deliberates on the construction of a fixed-time disturbance observer (FTDO)-based dynamic surface control (DSC) for attitude tracking of rigid spacecraft affected by asymmetric full-state prescribed performance (AFSPP) constraints. Distinct from conventional disturbance observers… read more here.

DOI: 10.1109/tcsii.2017.2710418

Abstract: This brief presents a fixed-time disturbance observer for Brunovsky systems. The proposed disturbance observer is composed of a uniform convergent part and a finite time convergent part. The uniform convergent part first drives the estimation… read more here.

DOI: 10.3390/sym14081704

Abstract: In practical applications, for highly nonlinear systems, how to implement control tasks for dynamic systems with uncertain parameters is still a hot research issue. Aiming at the internal parameter fluctuations and external unknown disturbances in… read more here.
