Optimization of jamming formation of USV offboard active decoy clusters based on an improved PSO algorithm

Defence Technology
Offboard active decoys (OADs) can effectively jam monopulse radars. However, for missiles approaching from a particular direction and distance, the OAD should be placed at a specific location, posing high requirements for timing and deployment.

High-Precision EV IPMSM and Loss Modeling for Real-Time Hardware-in-the-Loop Simulation Based on the Finite Element Method

IEEE Access
To address the insufficient accuracy of conventional linear models for interior permanent magnet synchronous motors in electric vehicles under high-load conditions, this paper proposes a finite-element data-driven nonlinear modeling and loss-integration ...

Adaptive multi‐level differential coupling control strategy for dual‐motor servo synchronous system based on global backstepping super‐twisting control

IET Control Theory & Applications
A new dual‐motor servo steering system with improved reliability and safety is proposed. But, despite the advantages of the proposed servo system, it is strongly coupled, non‐linear and multivariable, where the biggest challenge lies in its tracking and ...

Security threats : weapons of mass destruction?

, 1999
The end of the Cold War led many to believe that a reduction in weapons of mass destruction would follow. Instead it led to nuclear and ballistic missile proliferation. This reality posed a grave threat to security.
