For numerical simulation of detonation, computational cost using uniform meshes is large due to the vast separation in both time and space scales. Adaptive mesh refinement (AMR) is advantageous for problems with vastly different scales. This paper aims to propose an AMR method with high order accuracy for numerical investigation of multi-dimensional(More)
This paper considers the problem of robust H/sub /spl infin// control for uncertain continuous singular systems with state delay. The parametric uncertainty is assumed to be norm bounded. By using linear matrix inequality (LMI) approach, a sufficient condition is presented for a prescribed uncertain singular system with time-delay to have generalized(More)
We mainly research the method of designing the D-admissible controller for singular delta operator systems. In order to ensure that the generalized Delta operator system is D-admissible, we design a state feedback controller. According to the definition of the generalized discrete system and the generalized Delta operator system, the relationship between(More)
This paper investigates uncertain SDOSs (singular delta operator systems), regarding robust H∞ control and robust H∞ performance analysis. To ensure robust admissibility, we introduce the definition of generalized quadratic admissibility. Through LMI (linear matrix inequality), with the support of a necessary and sufficient condition, an(More)
