Stability of a Variable Coefficient Star-Shaped Network with Distributed Delay
Journal of Systems Science and Complexity - Tập 35 - Trang 2077-2106 - 2022
Hai-E. Zhang, Gen-Qi Xu, Hao Chen, Min Li
The paper deals with the exponential stability problem of a variable coefficient star-shaped network, whose strings are coupled at a common end in a star-shaped configuration and the common connection of all strings can be moved. Two kinds of media materials with a component of viscous and another simply elastic are distributed on each string. Under suitable hypothesis on the coefficient functions...... hiện toàn bộ
Adaptive set stabilization of the attitude of a rigid spacecraft without angular velocity measurements
Journal of Systems Science and Complexity - Tập 24 - Trang 105-119 - 2011
Shihong Ding, Shihua Li, Qi Li
The global adaptive set stabilization problem of the attitude of a rigid spacecraft is addressed in this paper. Two different cases are considered. First, by using adaptive backstepping method, the authors design a global adaptive control law for the attitude control system with unknown inertia matrix such that the attitude and the angular velocities can be globally asymptotically stabilized to a ...... hiện toàn bộ
Optimal allocation for estimating the correlation coefficient of Morgenstern type bivariate exponential distribution by ranked set sampling with concomitant variable
Journal of Systems Science and Complexity - Tập 26 - Trang 249-260 - 2013
Minyu Xie, Ming Xiong, Ming Wu
Ranked set sample is applicable whenever ranking of a set of sample units can be done easily by a judgement method of the study variable or of the auxiliary variable. This paper considers ranked set sample based on the auxiliary variable X which is correlated with the study variable Y, where (X, Y) follows Morgenstern type bivariate exponential distribution. The authors discuss the optional alloca...... hiện toàn bộ
Practical Exponential Stability of Two Dimensional Nonlinear Switched Positive Systems in the Roesser Model
Journal of Systems Science and Complexity - Tập 36 - Trang 1103-1115 - 2023
Jie Zhang, Yuangong Sun
This paper deals with the practical exponential stability of two-dimensional (2-D) nonlinear switched positive systems with impulse, disturbance and all modes unstable. Under the mode-dependent interval dwell time switching, new criteria such that 2-D nonlinear switched positive systems achieve practical exponential stability are derived. Furthermore, the explicit upper bound and convergence rate ...... hiện toàn bộ
Cooperative Target Fencing of Multiple Vehicles for a General Target with Connectivity Preservation and Collision Avoidance
Journal of Systems Science and Complexity - - 2024
Zini Pan, Ben M. Chen
In this paper, the authors study the cooperative target-fencing problem for n-dimensional systems and a target with a general trajectory. Without using the velocity of the vehicles, a position feedback control law is proposed to fence the general target into the convex hull formed by the vehicles. Specifically, the dynamics of each vehicle is described by a double-integrator system. Two potential ...... hiện toàn bộ
Estimating the Size of an Open Population with Massive Datasets Based on a Generalized Varying-Coefficient Model
Journal of Systems Science and Complexity - Tập 35 - Trang 1116-1136 - 2021
Haoqi Li, Yuan Li
A generalized varying-coefficient model is proposed to estimate a population size at a specific time from multiple lists of an open population. The research datasets have millions of records with a very long time span (38 years), bringing challenges to calculations. The authors develop a regularization iterative algorithm to overcome this difficulty. The asymptotic distribution of the proposed est...... hiện toàn bộ
