A mixed signal separation method based on RobustICA is proposed for the separation of the oil pipeline leakage signals. Due to the correlation between each source signal in pipeline transportation is very small, basically meet the requirements of statistically independent. Therefore, the RobustICA method is applied to the pipeline leakage monitoring and the leakage of the negative pressure wave signal...
To reduce conservatism, we adopted two approaches, pre-computing and/or free-weighting matrices, to manipulate the Lyapunov functional candidates, where we incorporate the more terms, and used them to analyse the robust control problem for uncertain stochastic systems with time-delay successfully. Then, we gave numerical examples to demonstrate the effectiveness of the two approaches.
This paper investigates the problems of delay-dependent robust H-infinity stability and stabilization for uncertain time-delay systems with stochastic perturbations. Some new delay-dependent stability criteria are devised by taking the relationship between the terms in the Leibniz-Newton formula into account. Free weighting matrices are used to express this relationship and the new criteria are less...
