This paper addresses conditions for characterizing static output feedback controllers including delays for some proper transfer functions. The interest of such study is in controlling systems which can not be stabilized by the classical, nondelayed static output feedback, and its difficulty lies in computing delay intervals guaranteeing closed-loop stability, since for the same matrix gain, sta...

Abstract: This paper discusses the quadratic stability and quadratic stabilization problem for a class of nonlinear perturbed discrete time-delay systems. Necessary and sufficient conditions for quadratic stability are presented via S-procedure technique and linear matrix inequality (LMI). Both static and dynamic output feedback controllers are constructed respectively. Furthermore, necessary a...

Model-Based Networked Control Systems (MB-NCS) use a model of the plant to compensate for the lack of information between transmission times. This results in a significant reduction of the bandwidth used for stabilizing the control system. Previously published stability results for MB-NCS assume no quantization error. In this paper quantization is introduced for MBNCS. Sufficient stability cond...

this cross-sectional study aimed to determine the reliability of static control evaluation with synapsys posturography system (sps, marseille, france) and to compare the static postural control of deaf children with typically developing children. this study was conducted in 2 phases on 81 children of 7 to 12 years old in tehran schools. the first phase examined the reliability of static balance...

This paper presents a new integral control law for a boost converter that ensures the stability of large-signal operation. The integral controller is derived in two steps by means of passivitybased control theory. First, a static law, which ensures global stability, is obtained. Secondly, a combination of the storage function of this static law and a new positive semidefinite storage function r...

The design of a static output feedback fuzzy controller for nonlinear systems based on Takagi–Sugeno (T–S) fuzzy models is addressed. To avoid complex mathematical derivations and conservative results, a genetic algorithm (GA) is integrated with a linear matrix inequality (LMI) optimisation to seek the static output feedback gains that satisfy the Lyapunov stability inequalities with a decay ra...

Low power design has become the major challenge of present chip designs as leakage power has been rising with scaling of technologies. As modern technology is spreading fast, it is very important to design low power, high performance, and fast responding SRAM (Static Random Access Memory) since they are critical component in high performance processors. The Conventional 6T SRAM cell is very muc...

Over the last few years, the problem of voltage stability has received a lot of attraction from the power system community. This type of stability is now a major concern for utilities in both planning and operating conditions. Both static and dynamic aspects of the problem have been discussed and investigated by the researchers. The present paper concentrates on a Voltage Stability Analysis fun...

The static stability evaluation of tailing dam is one of the most important tasks in the mine environmental protection project. The methods for the static stability calculation were discussed in this paper, which were Swedish Circle Method, Janbu Method, Bishop Method, Finite Element Method and Strength Reduction Finite Element Method (SRFEM) with five different failure criterions considered. T...
