The classification and recognition technology of underwater acoustic signal were always an important research content in the field processing. Currently, wavelet transform, Hilbert-Huang Mel frequency cepstral coefficients are used as a method feature extraction. In this paper, for extraction identification noise data based on CNN ELM is proposed. An automatic signals proposed using depth convolution network. target classifier extreme learning machine. Although neural networks can execute...
Facing the complex marine environment, it is extremely challenging to conduct underwater acoustic target feature extraction and recognition using ship-radiated noise. In this paper, firstly, taking one-dimensional time-domain raw signal of ship as input model, a new deep neural network model for proposed. Depthwise separable convolution time-dilated are used passive first time. The proposed realizes automatic from data radiated noise temporal attention in process recognition. Secondly,...
This paper proposes a new detection model of weak signal based on third-order chaotic system. Using dynamic analysis tool, such as the Lyapunov exponent and bifurcation diagram, variations behavior can be observed, underwater picked up. In order to improve observability signals in time domain frequency domain, spectral entropy complexity algorithm (SE) C0 algorithms are used analyze extract signal. The experimental results show that spectrum extraction accurately reflect characteristics...
Adaptive feedback controllers based on Lyapunov′s direct method for chaos control and hybrid projective synchronization (HPS) of a novel 3D chaotic system are proposed. Especially, the controller can be simplified ulteriorly into single scalar one to achieve complete synchronization. The HPS between two nearly identical systems with unknown parameters is also studied, adaptive parameter update laws developed. Numerical simulations demonstrated verify effectiveness strategies.
In this paper, a comparative study is carried out on the six new switching tables and conventional table of direct power control (DPC) for voltage source rectifier (VSR). On basis mathematical model VSR, expressions variation active reactive are obtained. order to minimize errors between command estimated values power, appropriate vectors selected. Six constructed accordingly. Compared DPC, significant ripple reduction more sinusoidal line input current can be observed in DPCs. A further...
An applicable time-delay globally coupled map model using the symmetric (TDSG) is considered. Firstly, its rich dynamic behaviours are exhibited. Secondly, a parameter modulated control as type of adaptive method applied for associate memory, and then dynamics controlled system with time delay d = 1 elaborated. By means method, output TDSG runs along corresponding 2(d + 1) cycle periodic orbit change d. Moreover, stored pattern which has smallest Hamming distance to initial state network...
