Special Issue Information

Dear Colleagues, 

Fractional sliding mode control, a sophisticated technique rooted in fractional calculus, stands as a formidable asset for refining control mechanisms within the realm of robotics and dynamic systems. By crafting bespoke sliding mode surfaces, this method significantly amplifies the precision required for trajectory tracking in robotics while simultaneously fortifying resilience against external disturbances commonly encountered in dynamic systems. Moreover, its inherent adaptability curtails chattering phenomena, augments transient response capabilities, and optimizes control efforts, thereby fostering a more energy-efficient and stable operational paradigm. In essence, fractional sliding mode control emerges as an indispensable ally, adept at navigating the intricate challenges posed by contemporary control scenarios, and empowering systems with unparalleled precision, robustness, and efficiency amid complex and dynamic environments.

The article presents a novel control strategy for cable-driven aerial manipulators (UAMs) aimed at enhancing impedance control during contact operations in complex environments. A fractional-order nonsingular terminal sliding mode control (FONTSMC) integrated with a disturbance observer (DOB) is proposed to improve the robustness and precision of the UAM under lumped disturbances. This developed approach utilizes the flexibility of fractional calculus, the finite-time stability of nonsingular terminal sliding mode, and the real-time disturbance estimation capabilities of the DOB to ensure smooth and compliant contact interactions. The effectiveness of the proposed control strategy is validated through comprehensive simulation studies, which demonstrate significant improvements in control performance, stability, and disturbance rejection when compared to traditional methods. The results indicate that the FONTSMC-DOB framework is highly suitable for complex aerial manipulation tasks, offering both theoretical and practical insights into the design of advanced control systems for UAMs. Full article
