The performance of router directly impacts the Network-on-Chip (NoC) performance. This paper focus on developing efficient microarchitecture of allocator in the router and proposed matrix-diagonal allocator with high matching quality and low packets latency. The allocator, taking advantage of the fact that each element in the diagonal doesn't share the same row or column, includes matrix-diagonal...
The maintenance and management for the current Fourth Generation (4G) networks are still in a manual and semi-automatic manner, which are costly and time-consuming. This imposes a great challenge on the network management of heterogeneous, software-defined and virtualized Fifth Generation (5G) systems. With the advent of network intelligence, a possibility on intelligent management is opened for the...
This paper studies a group of interconnected memristor-based impulsive neural networks (MINNs) with time-delay and its synchronization mechanism. Due to the impulsive and switching mode, interconnected MINNs are mathematically elaborated in the form of impulsive differential inclusions. Based on theories of Lyapunov functions and impulsive differential equations, asymptotic convergence of synchronization...
Digital control of a general-purpose switching power supply is one of the key technologies to perform the high reliability and the intelligent functions demanded for the next generation. In this paper, the experimental identification method is firstly applied to the developed digital control-based switching power supply. Based on the identified model, the model-based control system is constructed...
A kind of photovoltaic water-pump control system based on digital signal processor TMS320F2812 is designed. An improved P&Q method for maximum power point tracking of solar array is adopted. The utilization efficiency of solar array is improved by this way. Besides the perfect running and fully-digital controlling are achieved by U / f constant control method which is based on SVPWM modulation...
The controllable metal oxide surge arrester is a kind of new electrical equipments which can deeply reduce switching overvoltage in UHV/EHV transmission system. Because of its unique structure, the conventional residual voltage test method could not be used to validate the protection effort of the controllable metal oxide surge arrester. It is necessary to find out an appropriate residual voltage...
Hybrid streaming delivery over converged mobile and broadcast networks can enable operators to transmit multimedia contents in a more efficient and flexible way. Consequently, the functions related to hybrid streaming delivery are recently standardized in the IP-based service layer standards for DVB-H, i.e. DVB-IPDC and OMA BCAST standards. In both standards, seamless service switching is one of the...
Ambient energy is a good supplement to existing hybrid power systems. Among the available options, solar is one of the most readily obtainable and technologically compatible sources. However, uncertainty of sun radiation intensity and changing atmospheric conditions impose challenges in efficient usage of sun power. Significant progress has been made during the last decades in optimally harvesting...
This paper introduced the operation principle of current mode control boost converter. The equations of two different work states were built by applying the theory of KCL and KVL. Two models working in CCM and DCM were respectively established using Matlab/Simulink and the nonlinear phenomenon of boost converter can be observed through simulation. The results of theoretical analysis are corresponded...
The operation principle of peak current mode control H bridge converter was analyzed. It can observe nonlinear phenomena in H bridge converter after simulating to the model, which builds by the concept of binary logic variables using Matlab/Simulink. According to the characteristics of H bridge converter, a time-delayed feedback control method was applied to suppress the chaos behavior of H bridge...
To improve the traditional direct torque control, bring in the stator field-oriented method, and introduce how to realize the quick response under the constant stator flux amplitude. Then directly calculate the accurate voltage vector values according to the angle that the flux goes across during a cycle and the difference between the flux's actual and desired values. In the last the space vector...
