This paper points and corrects mistakes in [Mathematical Problems in Engineering, Volume 2009, ID759248, doi:10.1155/2009/759248]. By introducing a Lyapunov-Krasovskii functional and using Jensen inequality technique to deal with its derivative, a delay-range-dependent and rate-dependent linear matrix inequalities (LMI) stability criterion for a class of neutral systems with time-varying neutral, discrete and distributed delays and nonlinear parameter perturbations is established. Compared with the corresponding result in [Mathematical Problems in Engineering, Volume 2009, ID759248, doi:10.1155/2009/759248], the new stability criterion not only removes the free-weighting matrices, but also is mathematically proven to be less conservative. Numerical examples are given to illustrate the advantages of the results obtained in this paper.

Reliable control problems for T-S fuzzy systems with sensor faults are studied in this paper. For a class of fuzzy systems, the premise variables of which are dependent on the system states, a type of new conditions for designing fuzzy reliable controllers are proposed by applying the properties of product inference engines. In contrast to the existing approach, the new conditions are with less conservatism for T-S fuzzy system with partly unmeasurable premise variables. An example is given to show the advantage of the proposed approach.

This paper designs a coupling adjustor for asymptotic synchronization of complex networks with a class of nonlinear sampling couplings. A version of the adaptive scheme is provided to adjust coupling strength for compensating for the adverse impact of sampling errors. Based on the Lyapunov stability theory, the asymptotic synchronization results of the whole networks can be obtained for nonlinear sampling couplings even without any control inputs. Finally, the proposed adaptive adjustment schemes are verified by an example on a Chua's circuit network.

A novel method to H∞ output feedback control of continuous-time switched linear systems is investigated in this paper. Base on multiple Lyapunov function method combined with the Projection lemma and Finsler's lemma, the resulting closed-loop system is stable and has a desire H∞ performance level γ under static and dynamic H∞ output feedback, respectively. Both these controllers are solved from strict linear matrix inequalities, which does not decompose Lyapunov matrix and its inverse matrix while a state-coordinate transformation is not required. The validity and advantage of the proposed method are illustrated using an example.

This paper studies the design and optimization method of Moon-Mars transfer trajectory with mixed propulsion technology. Previous researches imply that dividing the mission into three phases according to different three body dynamic system the explorer suffers sequentially can facilitate this design problem. Halo orbits about the Earth-Moon L2 and the Mars-Sun L1 points are chosen to insert to the transfer route, and the associated invariant manifolds are used to decrease the combustion. In the phases of Moon departure and Mars insertion, impulse jet is applied to reduce the required maneuver velocity pulse. In the heliocentric transferring phase, Fourier series are employed as the shape function to approximate the transfer trajectory with low thrust technology. Genetic algorithms with fuel consumption mass ratio as objective function are applied to seek out a less fuel consumption trajectory after sweeping the initial and final time of the interplanetary transfer. Simulation shows Moon-Mars transfer trajectory achieved by above methods consumes less fuel.

Hybrid consensus problems among a group of continuous-time high-order agents with directed communication topology are investigated by a time delay approach, where each agent obtains the communication information from its neighboring agents only at discrete-time instants. Firstly, based on both the continuous-time state information of each agent and the discrete-time communication information with time-varying sampling interval of its neighboring agents, a hybrid discrete/continuous consensus protocol is designed. Secondly, hybrid consensus problems are transformed into simultaneous stabilization problems of multiple sampled control subsystems with low dimensions by the state space decomposition approach. Thirdly, by using the time delay approach and linear matrix inequality (LMI) theory, sufficient conditions for hybrid consensus and consensualization are presented, where four LMI constraints are only included. It should be pointed out that the hybrid consensus for high-order swarm systems depends on the gain matrices, the spectra property of the Laplacian matrix, and the maximum sampling interval. Moreover, the consensus function is determined when swarm systems achieve hybrid consensus. Finally, numerical examples are given to illustrate the effectiveness of the theoretical results.

The dynamic fluid level of oil well is essential for the submersible motor. The prediction of dynamic fluid level is a popular research direction. This paper describes an approach to short-termly determine the dynamic fluid level by using the algorithm which combines the state space reconstruction and black hole least squares support vector machine (BH-LSSVM) algorithm together. The chaotic time series has to be reconstructed in the state space. Then based on the data of the reconstructed state space, the fluid levels will be determined dynamically, by using BH-LSSVM algorithm. The simulation results show that this algorithm has much higher accuracy on measurement of dynamic fluid level for oil well. It fulfills the requirements of the oil-well task. It can be deployed in oil well to measure the dynamic fluid level.

This paper addresses the robust stabilization problem for a class of cascade nonlinear switched systems subject to input saturation under asynchronous switching. Convex hull skills are utilized in order to deal with input saturation. A state feedback controller is proposed under the dwell time such that the resulting closed-loop system is exponentially robust stable.

A co-design of sampling rate scheduling and optimal control is investigated for networked control systems (NCSs) with transmission delay and packet loss. The basic purpose of proposed co-design scheme is to save substantial communication in both the sensor-to-controller channels and the controller-to-actuator channels, while guaranteeing optimal control performance of NCSs. Firstly, a switched systems model used to describe NCSs with sampling periods subject to a finite set is constructed. Secondly, guaranteed cost control is studied for NCSs in order to obtain two upper bounds of quadratic performance of systems under the two cases, (a): the worst network communication condition and the longest sampling period; (b): the best network communication condition and the shortest sampling period. After the above preparations have been done, a performance partition-based sampling rate scheduling algorithm is developed to perform co-design strategy for NCSs. Moreover, to calculate control performance in real-time approach and guarantee the asymptotically stable of systems, adaptive controllers are designed in terms of linear matrix inequality (LMI) technology. Finally, a numerical example and simulations are given to illustrate the effectiveness of the proposed method.

In this paper, we devote to investigating the consensus-based unscented Kalman filtering problem for a certain kind of sensor networks with sensor saturations. The communication status among sensors is represented by a connected undirect graph. Saturation phenomenon exists both in the state of the system and individual sensors. Moreover, a distributed unscented Kalman filtering algorithm based on CI (consensus on information) consensus approach is developed to estimate the ture state of interest. Finally, the effectiveness of the proposed consensus-based unscented Kalman filtering scheme is validated through a simulation example.
