[ 1 ] - Quantitative Non-diagonal Regulator Design for Uncertain Multivariable System with Hard Time-domain Constraints

In this paper a non-diagonal regulator, based on the QFT method, is synthesized for an uncertain MIMO plant whose output and control signals are subjected to hard time-domain constraints. This procedure includes the design of a non-diagonal pre-controller based on a new simple approach, followed by the sequential design of a diagonal QFT controller. We present a new formulation for the latter s...

[ 2 ] - آنالیز شکست پوسته­های استوانه­ای شیاردار تحت اثر انفجار داخلی به روش تحلیلی و شبیه سازی عددی

In this paper, a new method for fracture analysis of notched cylindrical cases under explosive loading of High Explosive internal charge has been presented to determine fracture time, fracture radius, fragment velocity and acceleration. Also the fracture dynamics has been simulated by explicit and nonlinear LS-DYNA code. In numerical simulation the behaviour of metallic case has been modeled by...
