Defect inspection of integrated circuits (ICs) solder joints is a long-standing task. This paper proposes a novel IC solder joint inspection method based on the idea of robust principle component analysis (RPCA), which is a celebrated optimization technique. To the best of our knowledge, this is the first time IC solder joint inspection is formulated as an optimization problem. In particular, we model...
In this paper, several new delay-dependent stability criteria are presented for a class of uncertain time-delay systems. Using an extended integral inequality, a new method is explored through the Moon's inequality and the Leibniz-Newton formula. The obtained results are less conservative compared with systems with the derivative of the time delay smaller than one, which is validated in a numerical...
The problem of global robust periodicity is studied for a class of neural networks with norm-bounded parameter uncertainties and multiple time-varying delays. Some linear matrix inequality (LMI) representations of delay-dependent periodicity criteria are presented to guarantee the existence, uniqueness and global asymptotic stability of periodic solution for all admissible parametric uncertainties...
This paper is concerned with robust dissipation problem for a class of uncertain neutral systems with multiple state delays. A static state feedback controller is designed to ensure the closed-loop system to be asymptotically stable and strictly (Q,S,R)-dissipative. Sufficient conditions are derived in the form of linear matrix inequality. The findings show that the solvability of the design problem...
