Abstract:This paper is concerned with the design problem of stability and stabilization of a class of nonlinear networked systems via output feedback control. The nonlinearity is assumed to be global Lipschitz. An output feedback control strategy on the basis of a new state observer is proposed. Sufficient stability condition for the closed-loop system is derived using switched Lyapunov function approach. By solving some linear matrix inequalities, the observer gains and controller gains can be obtained. A numerical example is presented to illustrate the efficacy of the proposed method. | |||

Abstract:The suspension system plays a crucial role of rail vehicles. The fault detection of the suspension system is an effective way to ensure the security, stable operation of rail vehicles. This paper concerns the fault detection issue of rail vehicle suspension systems with the extended form of Partial Least Squares(PLS), which is Multi-block Partial Least Squares (MBPLS). The signal information used in the fault detection is obtained from the SIMPACK and MATLAB co-simulation environment. In this paper, the typical primary spring and damper faults and secondary spring and damper faults are detected successfully using MBPLS. MBPLS is applied to the block data, and the statistical index and are used to monitor the performance of the suspension system. Compared with Dynamic Principal Component Analysis(DPCA), the effectiveness of the proposed approach is demonstrated by the simulation results for several fault scenarios of primary and secondary faults. | |||

Abstract:This paper presents an anti-windup compensation design for polytopic systems. A parameter-dependent anti-windup compensator is proposed to reduce the conservatism in correcting the possible saturation effect for LPV systems. Considering closed-loop performance within a guaranteed region of state space, stability conditions in LMI form are stated, by using quadratic functionals and a modified sector condition. Then the problem of the anti-windup compensation gain design is transformed into a LMI optimization problem. Numerical examples demonstrate the effectiveness of the proposed design approach. | |||

Abstract:This paper studies the state estimation issue for the linear system with intermittent and quantized measurements. The target of this paper is to design the quantization density $ho$ and the filter gain $L$ which can minimize the mean square error. From the analysis of package drop behaviour, we obtain the infimum of the quantization density $ho$. Under the assumption that covariance matrix is convergent, we can design the optimal filter gain $L$. Finally, an illustration example is shown to explain our results. | |||

Abstract:This admissible conditions (regular, impulse-free and stable) for a class of continuous-time Takagi-Sugeno (T-S) fuzzy descriptor systems areinvestigated. Based on a fuzzy Lyapunov function which is defined by fuzzily blending quadratic Lyapunov functions candidate, two sufficient admissible conditions for the closed-loop systems via parallel distributed compensation (PDC) and non-PDC feedback controller are proposed. By introducing relaxation matrix variables and descriptor matrix decomposition, the provided conditions can be obtained in terms of dilated Linear Matrix Inequalities (LMIs). Finally, a simulation example is given to illustrate the sufficiency of the proposed methods. | |||

Abstract:Consensus algorithm, which is constructed by introducing compensation on the neighboring agents' delayed states into the normal asynchronously-coupled consensusalgorithm, is proposed to solve the dynamical consensus problem of discrete-time second-ordermulti-agent systems with communication delay. By analyzing the consensus convergence of two coupled-agents according to frequency-domain analysis, we come to the conclusion that the compensation-based algorithm can endure higher communication delay than thesynchronously-coupled consensus algorithm. Based on linear fractional transformation and the small-gaintheorem, sufficient conditions are gained for discrete-time second-order multi-agent systems with communicationdelay under a general digraph. Simulation illustrates the correctness of the results. | |||

Abstract:In this paper, we address the adaptive Neural Network tracking control problem of switched nonlinear system with non-minimum phase subsystem based on RBF Neural Network. The proposed controller is comprised of a neural network adaptive law, an adaptive robust control term, and switching path. The approximation errors of the RBF neural networks are introduced to the design of the neural network adaptive law, while the switching path is designed by using the principle of "energy attenuation fastest". The proposed adaptive neural switching control scheme can guarantee that non-minimum phase switched nonlinear system can asymptotically track the desired reference signal. | |||
