PSO‐Nonsingular Fast Terminal Sliding Mode Control for Hexarotor in Turbulent Atmospheric Boundary Layer With Disturbance Observer

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Hexacopter operations in the atmospheric boundary layer (ABL) are affected by gusty winds and turbulence, leading to collision risks or crashes. Stability of the hexacopter UAV in gusty winds is challenging in urban space. In this paper, non‐singular fast terminal sliding mode control (NFTSMC) is optimized using particle swarm optimization for

Nonfragile Sliding Mode Control of Fractional‐Order Complex Networked Systems via Combination Event‐Triggered Approach

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This work addresses the problem of developing a nonfragile sliding mode observer for fractional‐order complex networked systems (FO‐CNS) under stochastic network attacks. The proposed approach employs a combination of event‐triggered techniques. First, a nonfragile fractional‐order state observer is developed, enabling the design of a suitable

A Fully Automated Robotic System for Tuning Optimization of RF Cavity Filter

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The advancements in radar systems, electronic warfare, and telecommunication industries have generated a substantial demand for microwave filters. Among these, cavity filters have conventionally served in transmitters and receivers, facilitating the passage of desired signals in the passband while effectively rejecting harmonics and spurious ...
