A new DBSCAN clustering based niching GA (DCNGA) algorithm that used to locate all global optima in uneven multimodal domain is presented in the paper. In order to remove some a priori knowledge requirements of standard sharing, such as peaks number and sharing distance, DCNGA using DBSCAN clustering algorithm to identify the niche automatically, and(More)
On the basis of artificial neural network theory, this paper has put forward a new kind of speed observer. The observer is good in robustness of motor parameter changes, high in the observation precision. The speed identification convergence is fast, especially keeping higher precision in low speed. At the same time, the paper puts forward a new method of(More)
This paper presents a novel Matching Propagation Framework for addressing the problem of finding better matching pairs between each two images, which is one of the most fundamental tasks in computer vision and pattern recognition. We first select initial seed points by original matching method like SIFT, and then use T-CM to explore more seed points.(More)
The modeling and stabilization for a class of non-uniformly sampling multiple-input-multiple-output (MIMO) networked control systems (NCSs) with limited communication resources is studied in this paper. Firstly, by using lifting techniques, the extended MIMO model for NCSs is described. Furthermore, based on the new model, sufficient conditions for the(More)
For the networked multi-agent system with arbitrary-order time-delayed agent dynamics, the parametric H<sub>&#x221E;</sub> design method of the decentralized PID controller is proposed in this paper. The closed-loop framework representation is first given for the multi-agent system with the decentralized PID controller imposed on each agent. Based on this(More)
The problem of controller design for a class of multiple-input-multiple- output(MIMO) networked control systems with limited communication resources is studied in this paper. Firstly, by using the notion of communication sequences and non-uniformly sampling methods, a extended MIMO model for NCSs with communication constraints is described to an integrated(More)
Process knowledge discovery is a significant research field in enterprise management. Based on process knowledge complexity and specialty, a process knowledge discovery model is presented in this paper according to multi-agent technology for full life-orientation of the product which is a solid foundation for an enterprise seeking optimal process(More)
