Coordinated Control and Estimation of Multiagent Systems with Engineering Applications
Recently, coordinated control and estimation problems have attracted a great deal of attention in different fields especially in biology, physics, computer science, and control engineering. Coordinated control and estimation problems have prominent characteristics of distributed control, local interaction, and self-organization. Research on multiagent coordinated control and estimation problems not only helps better understand the mechanisms of natural collective phenomena but also benefits the applications of cyberphysical systems.
This special issue focuses on theoretical and technological achievements in cooperative multiagent Systems. It contains twenty-six papers, the contents of which are summarized below.

(2) Distributed Estimation and Control for Mobile Sensor Networks. Y. Bo et al. “Improved Different Dimensional Sensors Combined Space Registration Algorithm” studied a method based on the state value and space deviation of federated filtering of unscented Kalman filter and standard Kalman filter, which conduces to real time registering of system deviation of radar and IF sensors. B. Yan et al. “Robust Fault Detection for a Class of Uncertain Nonlinear Systems Based on MultiObjective Optimization” presented a robust fault detection scheme for a class of nonlinear systems with uncertainty. The proposed approach utilizes robust control theory and parameter optimization algorithm to design the gain matrix of fault tracking approximator (FTA) for fault detection. The design of the gain matrix of FTA takes into account the robustness of residual signals to system uncertainty and sensitivity of residual signals to system faults simultaneously, which leads to a multiobjective optimization problem. Then, the detectability of system faults is analyzed by investigating the threshold of residual signals. W. Liu et al. “Energy-Efficient Node Scheduling Method for Cooperative Target Tracking in Wireless Sensor Networks” proposed an energy-efficient node scheduling method is proposed to minimize energy consumption while ensuring the tracking accuracy. The proposed scheduling method can keep the tracking accuracy while minimizing energy consumption and the NP-complete nature is avoided. B. Yan et al. “Distributed Fault Detection for a Class of Nonlinear Stochastic Systems” presented a novel distributed fault detection strategy for a class of nonlinear stochastic systems, in which a nonlinear fault detection filter was constructed to provide estimation of unmeasurable system states and residual signals using outputs of the consensus filter.
