Crustal movement is a key factor affecting water cycle and related land surface processes. In this paper, the principle of a class of crustal movement simulation system (CMSS) is introduced. The CMSS proposed in this study is composed of twelve sets of four-legged parallel manipulator with three degrees of freedom. The structure of the parallel manipulator with actuation redundancy is analyzed. In...
The synchronization control of Lu chaotic systems is focused on this paper, by using the controller designed by Zhang dynamics (ZD) method, with only one input. The ZD method is a handy and simple method for designing control input. The controller, designed by ZD method, is able to synchronize Lu chaotic systems. Engineering-type steady-state analysis is given to confirm the efficacy of the controller...
This paper is concerned with the synchronization problem for complex dynamical networks with time-varying coupling delay and sampled-data. The sampling period considered here is assumed to be time-varying but bounded. A novel exponential synchronization condition is established based on the Gronwall's inequality, and an explicit expression for a set of sampled-data synchronization controllers is also...
In the paper, the synchronization control problem for a class of uncertain master-slave dynamical system is investigated by using the adaptive control method. In order to overcome the disadvantage of the uncertainty in the dynamical system, a novel adaptive controller is constructed. Based on the stability of stochastic differential equation, some sufficient conditions which ensure that the master-salve...
In the paper, we firstly give a new accurate spheroid estimation formula of the globally exponentially attractive set for all positive parameters by constructing a generalized positive definite Lyapunov functions with radially unbound. Secondly, based on inequalities techniques, linear feedback control with one input or two inputs is proposed to realize the globally exponential synchronization of...
In the paper, the globally exponential synchronization of a new 3D chaotic systems are investigated. Based on some inequalities techniques, linear feedback controls both with one input and one state or two states and with two inputs and one state or two states are proposed to realize the globally exponential synchronization of two identical chaotic systems. Some sufficient conditions for the globally...
In this paper, complete synchronization is considered for the delayed neural networks with discontinuous activation functions. Under the framework of Filippov solution and in the sense of generalized derivative, a novel control method is given by using approximation and linear matrix inequality (LMI) approach. Based on the detailed analysis of previous works, several criteria are derived to ensure...
This paper deals with global synchronization in arrays of coupled Lur'e systems with nonlinear delayed coupling. Together with Krasovskii-Lyapunov functional and Kronecker product technique, two novel synchronization criteria are presented in terms of linear matrix inequalities (LMIs) based on convex combination, in which the conditions are heavily dependent on the bounds of time delay and its derivative...
We consider the coordinated attitude control problem for a group of spacecraft without velocity measurements. Our approach is based on the introduction of an auxiliary dynamical system for each spacecraft (playing the role of velocity observers in a certain sense) to generate the individual and relative damping terms in the absence of the actual angular velocities and relative angular velocities....
