In collisions with trucks, there is a high risk for car occupants to sustain severe or fatal injuries. The intelligent rear under-run protection system, as a very important part to prevent under-run accidents and decrease loss, its dynamic deformation and stress distribution mostly lie on the characteristic of energy absorber and keeping directional stability of the rear vehicle during collision....
An optimal design approach to fault detection with H_ index and Hinfin norm for linear time invariant systems is proposed. At first a linear full-order observer is constructed and the dynamics of residual generator which involves unknown inputs represented by disturbances, noise, model uncertainty and faults is acquired. The sensitivity of residual to faults is characterized by H_ index, and the robustness...
