This paper investigates the controller design problem for networked control systems (NCSs). By considering the relationship between the network-reduced delay and its upper bound, an improved stability criterion for networked closed-loop system is proposed without ignoring any terms in the derivative of Lyapunov-Krasovskii functional. As a result, a state(More)
The free-weighting matrix approach is employed to investigate the output feedback control of linear discrete-time systems with an interval time-varying delay. First, a delay-dependent stability analysis is carried out using a new method of estimating the upper bound on the difference of a Lyapunov function without ignoring any useful terms; and a design(More)
A comprehensive discussion on the potential conservatism of a descriptor model transformation approach is given and the stability/stabilization of time-delay systems are reconsidered by using an integral inequality recently established. A refined delay-dependent stability condition, which includes the one by the descriptor model transformation approach as a(More)
This paper is concerned with the stability analysis for uncertain stochastic systems with interval time-varying delay. Improved delay-dependent robust stability criteria of uncertain stochastic systems with interval time-varying delay are proposed without ignoring any terms by considering the relationship among the time-varying delay, its upper bound, and(More)
This paper deals with the problem of delay-dependent robust stability for uncertain stochastic systems with time-varying delay. Improved delay-dependent robust stability criteria are proposed without ignoring any terms by considering the relationship among the time-varying delay, its upper bound and their difference, and using both Itpsilas differential(More)
This paper implements a 14-bit successive approximation analog-to-digital converter (SAR ADC) design. The architecture and performance of the designed ADC is described. A digital calibration algorithm applied in this ADC has been emphasized in this paper. The correction codes of the calibrated capacitor are generated from the low bit to the high bit in the(More)

By reviewing the number of efficient schemas that are disposed by partheno-genetic algorithm during every genetic operation, the mathematics formula researching the optimal population size of partheno-genetic algorithm is presented, and then the existence of optimal population size of partheno-genetic algorithm is demonstrated. One of the key problems in(More)
Precision irrigation is an important practice in water-saving agriculture cropping system, which allows producers to maximize their productivity while saving water. While the accurate irrigation amount is difficult to obtain as the impact factor was too much. In order to solve this problem, a fuzzy decision-making method of irrigation amount based on ET and(More)
The carbon-monoxide utilization ratio (CMUR) is a significant factor for the energy consumption in the blast furnace (BF). CMUR cannot be well controlled on the spot due to the low predication in the previous research. In this paper, a chaotic prediction method is presented to forecast the variation tendency of CMUR. Firstly, CMUR time series sample data(More)
BACKGROUND The time required for patients with acute chest pain to reach a hospital emergency department varies, possibly lowering the diagnostic performance of a general cut-off value for high-sensitivity cardiac troponin T (hs-cTnT) in diagnosing acute myocardial infarction (AMI). The aim of this study was to determine the cut-off values as calculated by(More)
