anewLMSalgorithm
说明： 本文对变步长自适应滤波算法进行了讨论,建立了步长因子μ与误差信号e(n) 之间另一种新的非线性函数关系. 该函数比已有的sigmoid 函数简单,且在误差e(n)接近零处具有缓慢变化的特性,克服了Sigmoid 函数在
自适应稳态阶段步长调整过程中的不足. 由此函数本文得出了另一种新的变步长自适应滤波算法,并且分析了参数α,β的取值原则及对算法收敛性能的影响. 该算法有较好的收敛性能且计算量少. 计算机仿真结果与理论分析相一致,证实了该算法的收敛性能优于已有的算法.(In this paper, variable step adaptive filter algorithm to discuss the establishment of a step factor μ and the error signal e (n) between another new nonlinear function. The function has a sigmoid function than the simple and the error e (n) close to zero Department has a slow change in the characteristics of a Sigmoid function to overcome the steady-state phase in the adaptive step length adjustment during the process. this function, this paper gives another new variable step size adaptive filtering algorithms, and analysis of the parameters α, β the value principles and the convergence performance. The algorithm has better convergence performance easy to calculate. Simulation results and theoretical analysis, confirmed the convergence of the algorithm better performance than existing algorithms.)

solarstreetlight
Study of a DC-DC Converter for Solar LED Street Lighting:
Recently, light-emitting diodes (LEDs) are becoming increasingly attractive lighting sources in our daily lives. They are well suited to indoor and outdoor energy-saving lighting applications, such as general lighting, architectural lighting, traffic lighting, background lighting, displays, street lighting, automotive and motorcycle lighting, decorative lighting, and so on.
The placement of street lights is closely related to the development of one area or region, and they represent the financial success of a city. For street lighting applications, the traditional lighting sources are high-pressure sodium lamps and high-pressure mercury lamps. Recently, LEDs are commonly being used as new sources for street lighting because of their attractive features of good lighting efficacy, energy-savings, that they are non-polluting to our environment, and that they offer a long lifetime in comparison to their traditional counterparts.
