This paper studies the stability of linear systems with interval time-varying delay and nonlinear perturbations. By developing a new delay-dependent decomposition approach, a new delay-fractional-dependent Lyapunov-Krasovskii (LK) function is constructed, and then stability criteria are derived by employing the convex optimization technique. Since that a tuning parameter is employed to variable delay...
There is a theoretical analysis of torsion beam rear suspension on oversteer caused by roll steer of rear axle, and several measures to weaken oversteer are proposed. Then, establishing the flexible multi-body model for the conventional Torsion beam rear suspension and the improved by Hyperworks and Adams, a cornering force is applied to the torsion beam suspension to simulate the condition of vehicle...
The design principle, aviation mechanics and stability of a vertical take-off and landing vehicle is investigated in this paper. Based on these flight parameters, structural and dynamic parameters are determined. With aids of the methods of kinematics, aerodynamic and dynamic analysis, the theoretical lift provided by this ducted lift propellers and thrust produced by forward ducted propeller are...
In this paper, we propose a wavelet lossy image coding algorithm with edge detection and tracking using wavelet difference reduction. Firstly, we obtain the edge map of an obstacle image by SUSAN edge detector. And an edge tracking filtering method is applied to the edge information image and Region of Interest (ROI) is extracted from the original image. Then the coordinates of ROI are mapped to the...
