Water supply system has characteristics of non-linear, time-varying parameter, large time delay, so its mathematical model changes time by time. Water supply system widely use PID controller to keep constant pressure and PID controller need accurate mathematical model. The system that use PID controller is along with large overshoot, more adjusting time. Fuzzy controller don't need the accurate mathematical...
Delay tolerant network (DTN) routing provides a communication primitive in intermittently disconnected networks, such as battlefield communications and human-contact networks. In these applications, the anonymity preserving mechanism, which hides the identities of communicating parties, plays an important role as a defense against cyber and physical attacks. While anonymous routing protocols for DTNs...
Due to intermittent connectivity and uncertain node mobility, opportunistic message forwarding algorithms have been widely adopted in delay tolerant networks (DTNs). While existing work proposes practical forwarding algorithms in terms of increasing the delivery rate and decreasing data overhead, little attention has been drawn to the control overhead induced by the algorithms. The control overhead...
In Opportunistic Mobile Networks (OppNets), data is opportunistically exchanged between nodes who encounter each other. In order to enable such data exchanges, nodes in the network have to probe their environment continually, so as to discover neighbor nodes. This can be an extremely energy-consuming process. If nodes probe very frequently, they will consume a lot of energy, and might be energy inefficient...
Cooperative communication (CC) has been proposed recently as an effective way to mitigate channel impairments. It has been shown that cooperative communications have the potential to significantly increase the capacity of wireless mesh networks (WMNs). However, most of the works focus on single channel based WMNs. In this paper, we will demonstrate how the cooperative communication benefits multi-channel...
Iterative learning control method is proposed for the single pendulum which is a typical fast-speed multi- variable nonlinear absolutely unstable system. The closed loop iterative learning algorithm based on Lyapunov theory is presented, where the sufficient condition of convergence for closed loop iterative learning algorithm is proposed. The closed loop iterative learning control gains are designed...
This paper addresses the problem of non-stationary signal noise suppression, represents the conception of wavelet transformation and puts forward two kinds of measurements to evaluate the effectiveness of noise suppression. Comparison experiments for noise suppression are made using Fourier analysis and Wavelet analysis. Simulation result shows that Wavelet analysis is more suitable for non-stationary...
