This paper investigates the cluster consensus problem of heterogeneous multi-agent systems, where the considered systems are composed of first-order dynamics and second-order dynamics. The consensus protocol is designed to converge the position and velocity states of the heterogeneous multi-agent systems in two separate location. Stability analysis for heterogeneous multi-agent systems is presented...
This paper investigates the second-order consensus problem for multi-agent systems with random link failures between each agent. The discrete-time multi-agent systems are described by the second-order dynamics, and the communication network is assumed to be directed with fixed topology. Since each link between the agents can be subject to failure with a certain probability, the control protocol is...
In this paper, memory reduction method using the Sub-PFP is proposed. That is, two-dimensional PFPs in conventional N-LUT method can be converted by one-dimensional Sub-PFPs using trigonometric relations. Some experiments with a test 3-D object are carried out and the reduction ratio of LUT is analyzed.
In this paper, the stochastic observer based H∞ control problem is investigated for the networked control systems(NCS) with packet dropouts. Packet dropout is modeled by Bernoulli probability sequence, which presents transmitted data through the network channel. Based on the existence of the packet dropout, the appropriate Lyapunov-Krasovskii functional and the linear matrix inequality(LMI) method...
In this paper, we present a non-fragile guaranteed cost control design method for uncertain systems with time- varying delays in state and control input, even though the controller gain is perturbed. The uncertain nonlinear term in the systems is norm bounded and the linear matrix inequality(LMI) optimization method is employed as a stability analysis of the systems. We design a robust controller...
In this paper, we present the adaptive wavelet neural network (WNN) controller, which is trained by adaptive learning rates (ALRs), as an active queue management(AQM) in end-to-end TCP network. In TCP network, AQM is important to regulate the queue length and short round trip time by passing or dropping the packets at the intermediate routers. RED and PI algorithms have been used for AQM formerly...
