Inherent high switching frequency ability makes silicon carbide Metal-Oxide-Semiconductor Field-Effect transistor more sensitive to the parasitics and noise in the circuit. The layout of gate driver has a crucial influence on the parasitics, hereby the propagation delay and rise/fall time of the driving signal which is among the dominant factors to determine the switching performance of power device...
In this paper, a genetic algorithm based converter system design procedure is presented with the feature of speed and universal. This method can better pack a high power density power converter.
Vehicle identification is one of the frequently studied problems in video surveillance. Commonly, identifying an unknown vehicle object requires a large amount of training instances. Unfortunately, in the large parking scenario, the cost may be prohibitively expensive because of the finitely waiting time from the car owners. In this paper, we show that it is possible to identify a registered vehicle...
In the battle of anti-air attack, the troops have to carry out the electronic jamming by integrated using of electronic measures in order to weaken the airborne Radar detection ability for the enemy. The allocation of jamming arms plays important role in influencing the jamming benefit directly. In this paper, we propose an arms allocation model for Radar jamming system based on the chaos genetic...
In recent years, Rayleigh waves are gaining popularity to obtain near-surface shear (S)-wave velocity profiles. However, inversion of Rayleigh wave dispersion curves is challenging for most local-search methods due to its high nonlinearity and to its multimodality. In this study, we proposed and tested a new Rayleigh wave dispersion curve inversion scheme based on differential evolution (DE) algorithm...
A variable structure control law is presented according to a generic hypersonic vehicle model. First, the model is transformed into an affine system through input-output feedback linearization. Then, a structure of the control law is designed for the affine system. After the structure design of the control law, all control parameters of the control law are optimized based on a genetic algorithm. On...
A modeling method based on genetic neural network used for book purchasing is put forward on account of lacking of a set of scientific and uniform purchasing mode and model in current book purchasing process. This method improves standard genetic algorithm first, and then uses the improved standard genetic algorithm as a method of feed forward neural network training and threshold value of feed forward...
Through analysis of present pseudo-parallel genetic algorithm, propose a new dynamic sub-population pseudo-parallel genetic algorithm. It changes the condition that the magnitude of sub-population is stationary in current information exchange model, the magnitude of sub-population will change with the evolution. This algorithm can not only restrain premature convergence, but also get global values...
Based on the movement model of a waterjet propelled craft, an autopilot control system with adjustable control parameters for a waterjet propelled craft is designed by fuzzy control and genetic algorithms. The normal fuzzy controller is improved by the modified factor and the correction, and uses genetic algorithms to optimize all parameters to get the global solution. The controller can on-line tune...
This paper proposes an improved genetic algorithm (GA) assisted beamforming for a one-dimensional linear antenna array. Its performance of random interference nulling is studied. We design an improved binary code method for GA, which introduces several parameters to conveniently control the solution precision and search space. The simulation results show that the improved algorithm can efficiently...
This paper presents an improved genetic algorithm assisted beamforming, which introduces several parameters to conveniently control the solution precision and search space. The performance of low sidelobe wide nulling and the convergence are discussed for a one-dimensional linear antenna array. The simulation results show that the algorithm can efficiently give a wide nulling of 30 dB and has good...
