The paper deals with the observation problem by using an infinite dimensional observer for the water wave system governed by linearized water wave partial differential equations. We consider that the water wave system evolves in some infinite-dimensional Hilbert space. The output measurement of dynamical system is supposed to be the water wave surface elevation. An infinite-dimensional exponentially convergent Luenberger-like observer is proposed to estimate the states of water water system: water velocity potential and surface elevation. Numerical simulations by the finite difference scheme are carried out to validate the proposed observer.

Network is the core element of many industrial and automation systems. In the future, more attention will be paid to convergent and unified network. Time-critical traffic and non-time-critical traffic need to share communication channels. The goal of the IEEE TSN task group is to extend the existing Ethernet standard to achieve a degree of certainty that meets the hard-real-time requirements of modern control networks in the industrial automation and automotive industries. Time sensitive network (TSN) is characterized by low jitter, low delay and deterministic transmission. It can transmit critical and non-critical traffic in the same network, which is very suitable for time- critical applications with high requirements on transmission delay. This paper briefly summarizes the key components of TSN, studies the key technologies, and carries out a simple traffic scheduling experiment on the switch based on 802.1Qbv function, and finally analyzes the application of TSN in industrial automation and automobile industry.

In this paper, with the aid of Zhang dynamics（ZD） method, the ZD controller is designed for output tracking, setting,zeroing and maintaining of time-varying linear（TVL） system. One can see in this paper that ZD controller is an effective controller for output tracking, setting, zeroing and maintaining of TVL system, which can be guaranteed by theoretical ***, to simulate the practical conditions, we make use of ordinary difference equation（ODE） solver to conduct numerical experiments with such a second order TVL system. To verify the efficacy of ZD controller designed for output tracking, setting,zeroing and maintaining of TVL system, we choose different tracking, setting, zeroing and maintaining examples to conduct numerical experiments. By exploiting ZD controller, the error between system output and its desired function practically converges towards zero and remains stable. Numerical experiments verify the efficacy of ZD controller designed for output tracking,setting, zeroing and maintaining of TVL system. It also means that ZD method can also be applied to output tracking, setting,zeroing and maintaining of TVL system, which may just be a small part of potential applications of ZD method.

This paper investigates the generalized projective synchronization scheme of a new fractional chaotic system, which can display a four-wing chaotic attractor when the order of system is in the range of 0.82 and ***, considering the situation with unknown parameters, an adaptive nonlinear controller is obtained for synchronization and parameters identification based on fractional-order Lyapunov stability theorem. The fractional-order adaptation law, which can update parameters estimation errors online, is derived to ensure the stability of synchronization error system. Numerical simulations are used to verify the results.

Due to energy and environment demands, as well as a developing trend of magneto-rheological (MR) semi-active suspension, the study on key technologies of the novel MR power regenerative suspension system, in which a tubular linear permanent-magnet synchronous motor (TPMLM) is equipped in parallel with MR damper (MRD), has important theoretical and engineering significances. In this paper, the dynamical model of the MR suspension and finite element model of TPMLM are established, respectively, so as to set up the combination simulation platform of the regenerative suspension system. The frequency response is observed to reveal the influence of the installed TPMLM on vehicle suspension characteristics. Further, the semi-active suspension performance and regenerated power are analyzed under the harmonic and random road surface excitations to verify and improve the proposed design method. The proposed MR regenerative suspension is potentially valuable in application of new energy automobiles especially electric vehicle. © 2018 IEEE.

This paper introduces Zhang neurodynamics(ZN) method and Zhang-gradient(ZG) method used to design ZN and ZG controllers for the output tracking of systems, especially time-varying nonlinear system. Thereinto, ZG method is composed of the ZN method and gradient neurodynamics(GN) method. By applying the ZN method and the ZG method, respectively, to the output tracking control problems of time-varying linear(TVL) system and time-varying nonlinear(TVN) system, specific ZN controllers and ZG controllers are obtained. Particularly, TVL system and TVN system discussed in this paper may both have pseudo division-by-zero phenomena. From the numerical results, though ZN controllers and ZG controllers perform the output tracking of TVL system and TVN system well, the infinite value of the former and the finite value of the latter at singular instants verify that the ZG method is more effective in dealing with pseudo division-by-zero problem.

For quadratic minimization(QM), it is usually assumed that the solution objective is time-invariant and at the same level. However, the QM is always time-varying(i.e., naturally and implicitly dynamic) and may be at different levels(i.e., explicitly dynamic) in practice. In this paper, different from the general QM, a novel different-level dynamic QM(DLDQM) is proposed and investigated. First, the DLDQM solving is split up into two general time-varying QM(TVQM) solving. Then, a solution model is thus proposed and investigated for the DLDQM, by applying square root matrix based Zhang equivalency and Moore-Penrose(MP) generalized inverse. In addition, it is worth pointing out that solving the DLDQM is a new and important attempt of this research. Finally, illustrative numerical experiments are conducted with numerical results presented and analyzed.
