This paper concerns with the master-slave exponential synchronization analysis for a class of general Lur'e systems with time delay. Different from the previous methods based on the differential inequality technique, a new approach is proposed to derive some new exponential synchronization criteria. The restriction that the control width has to be larger than the time delay is removed. This leads to a larger application scope for our method. Moreover, no transcendental equation is involved in the obtained result, which reduces the computational burden. Two examples are given to validate the theoretical results. 相似文献

Based on the LaSalle invariance principle, we propose a simple adaptive-feedback for controlling the unified chaotic system. We show explicitly with numerical proofs that our method can easily achieve the control of chaos in the unified chaotic system using only a single variable feedback. The present controller, to our knowledge, is the simplest control scheme for controlling a unified chaotic system. 相似文献

The effects of time-delayed feedback control in a single-mode laser
system is investigated. Using the small time delay approximation,
the analytic expression of the stationary probability distribution
function of the laser field is obtained. The mean, normalized
variance and skewness of the steady-state laser intensity are
calculated. It is found that the time-delayed feedback control can
suppress the intensity fluctuation of the laser system. The
numerical simulations are in good agreement with the approximate
analytic results. 相似文献

Global chaos synchronization of two identical nonlinear transducer systems is investigated via linear state error feedback control. The sufficient criterion for global chaos synchronization is derived firstly by the Gerschgorin disc theorem and the stability theory of linear time-varied systems. Then this sufficient criterion is further optimized in the sense of reducing the lower bounds of the coupling coefficients with two methods, one based on Gerschgorin disc theorem itself and the other based on Lyapunov direct method. Finally, two optimized criteria are compared theoretically. 相似文献
