Stability of systems with state delay subjected to digital control

Stability of linear delayed systems subjected to digital control is analyzed. These systems can typically be written in the form ẋ(t) = Ax(t) + Bx(t− τ) + Cx(tj−1) , t ∈ [tj , tj+1) , where tj = j∆t with ∆t being the sampling period for the digital controller. The point-delay term x(t−τ) is assumed to be inherently present in the governing equation of the uncontrolled system, while the term x(t...

Evaluation of Buckling and Post Buckling of Variable Thickness Shell Subjected to External Hydrostatic Pressure

Buckling and post buckling of cylindrical shells under hydrostatic pressure is regarded as important issue in structure of submarines. These cylindrical shells have variable thickness due to construction process which effected by pressure of buckling and its destruction. In this paper, effects of changing thickness on buckling and destruction pressure under external hydrostatic pressure of a sh...
