A reduced-order delay-dependent H∞ filter design method for singular Markovian jump systems with mode-dependent time delay is studied in this paper. The purpose is to design linear filters with specified order lower than the given system such that the filtering error system is regular, impulse free, mean-square exponentially stable, and satisfied a prescribed H∞ performance index. One major contribution...
In this paper, the chaotification problem of a class of stable smooth-air-gap permanent magnet synchronous motor (PMSM) system is investigated. First, the smooth-air-gap PMSM plant is exactly represented by a simple T-S fuzzy model with a few fuzzy rules. Then, a nonlinear delayed feedback controller is designed by parallel distributed compensation technique. In addition, it is proved that the chaos...
In this paper, the delay-dependent non-fragile robust H∞ control for a class of fuzzy descriptor time-delay systems with norm-bounded parameter uncertainties is investigated. First, a new delay-dependent non-fragile H∞ stabilization method is proposed via a state feedback fuzzy controller, which guarantees the closed-loop nominal system to be regular, impulse free, asymptotically stable. Then, sufficient...
In this paper, the delay-dependent non-fragile H∞ control for a class of fuzzy descriptor time-delay systems is investigated. A non-fragile controller via state feedback is proposed, which guarantees the closed-loop system to be regular, impulse free, asymptotically stable and satisfies the H∞-norm constrain. The sufficient conditions for the solvability of this controller design problem are presented...
When locating the rub-impact source of rotating machines by acoustic emission technology, precise time-difference of arrival is always not available to calculate the faults location due to the deteriorated signal correlation relationship among different sensors. This is caused by both the dispersion phenomenon since the acoustic emission signal includes various waveform modes while each type of waveform...
The notions of the (strongly) practical stability in probability and in the pth mean, are introduced for some large-scale stochastic systems with Markovian jump parameters and time-varying delays. Sufficient conditions on such practical properties are obtained by using the comparison principle and the Lyapunov function methods.
This paper presents a method for analysis and control of discrete-time piecewise linear time-delay systems based on a piecewise Lyapunov functional. It is shown that the stability and stabilization conditions can be formulated and solved by a set of linear matrix inequalities (LMIs) and the less conservative results can be obtained. Numerical examples are given to illustrate the effectiveness of the...
