Abstract:This paper addresses the numerical conditioning problem that arises in the continuous-time system identification case. To solve this problem, a new frequency domain weighted least squares estimator using matrix orthogonal polynomial basis (MOPB) is proposed, which allow us to model transfer function matrix without vector operation, and yield perfect condition number. The key idea is to expand the matrix fraction description model on MOPB. The construction of MOPB is described in this paper and the efficacy of this method is illustrated with a numerical example. | |||

Abstract:Industrial Wireless Sensor Networks (IWSNs), a novel technique in the field of industrial control, can greatly reduce the cost of measurement and control, as well as improve productive efficiency. Different from Wireless Sensor Networks (WSNs) in non-industrial areas, IWSNs has high requirements for reliability, especially for large-scale industry application. As the network architecture has great influences on the performance of IWSNs, this paper discusses the node placement problem in IWSNs. Considering the reliability requirements, the setup cost and energy balance in IWSNs, the node placement problem in large-scale IWSNs is a non-linear constrained multi-objective optimization problem. In this paper, the node placement model of IWSNs is built and an adaptive mutation probability binary Particle Swarm Optimization algorithm (AMPBPSO) is proposed to solve this model. Performance comparisons show that the proposed AMPBPSO outperforms discrete binary Particle Swarm Optimization (DBPSO) and standard Genetic Algorithm (SGA) and AMPBPSO is more effective for the optimal node placement in IWSNs with various kinds of field scales and different node densities in terms of network reliability, load uniformity, total cost and convergence speed. | |||

Abstract:This paper investigates the H∞ filtering problem for a class of discrete time-varying Markovian jump systems. A full-order time-varying filter is constructed over a given finite-horizon, such that the H∞ disturbance attenuation level is guaranteed for the time-varying Markovian jump systems. The existence criterion of the desired filter is obtained in terms of a set of recursive linear matrix inequalities. A numerical example is presented to illustrate the effectiveness of the developed theoretical results. | |||

Abstract:In this brief, based on Lyapunov-Krasovskii functional approach and appropriate integral inequality, some new sufficient conditions are derived to guarantee the global asymptotically stability for neutral Lurie system with interval time-varying delay, in which the improved convex combination are employed. The LMI-based criterion heavily depends on both the upper and lower bounds on time delay and its derivative, which is different from the existent ones and has wider application fields than some present results. Finally, two numerical examples can illustrate the efficiency of the new method and reduced conservatism of the presented results. | |||

Abstract:This paper investigates the H∞ filtering problem for a class of nonlinear stochastic systems over limited capacity channel. The considered plant is described by a class of It^o stochastic time-delay systems with Lipschitz nonlinearities, and the output measurements are subject to logarithmic quantization before being transmitted in the network communication link. A new effective mathematical transformation is proposed to deal with the logarithmic quantization function. A H-infinity filter is designed for the stochastic system under consideration by employing the quantized output measurements. A numerical example is provided to illustrate the effectiveness of the proposed filtering technique in this paper. | |||

Abstract:This paper studies H-/H∞ control for MIMO singularly perturbed system(SPS) in finite frequency ranges. The sufficient conditions for the existence of an H-/H∞ sub-optimal controller are derived based on generalized KYP lemma. Moreover, the controller is also singularly perturbed. It is further shown that this controller is obtained through designing its fast and slow parts, and then the composite controller is established. The effectiveness of the proposed method is demonstrated through comparing with traditional H∞ design method. | |||

Abstract:A robust non-fragile H∞ control problems for neutral stochastic hybrid systems with time-varying delay are studied in this paper. Firstly, a delay-dependent stochastic Markov jumping bounded real lemma is presented in terms of linear matrix inequalities (LMIs). Secondly, based on the bounded real lemma, for the additive controller uncertainties, delay-dependent sufficient conditions for the solvability of non-fragile H∞ control for neutral stochastic hybrid systems with time-varying delay are derived by taking a Lyapunov-Krasovskii functional and its derivative. The desired state feedback controller can be developed by solving some certain LMIs. At last, a numerical example is given to show the validity of the obtained results and the effectiveness of the proposed method. | |||

Abstract:This paper discusses the exponential stability of nonlinear stochastic differential systems which coefficients obey the polynomial growth condition. Based on the stochastic analysis, we study the existence and uniqueness of the global solution of the nonlinear stochastic differential systems. Sufficient criteria on almost sure exponential stability and p-th moment exponential stability has been established. The new criteria is directly expressed in terms of the system coefficients and it can not only be applied much more easily but also cover a much wider class of nonlinear stochastic differential systems. The decay rate of almost sure exponential stability and p-th moment exponential stability are estimated through the system coefficients. Nontrivial examples with theirs numerical simulations are provided to illustrate our result. | |||
