This is one of the best otmization numeric method.

说明：  程序描述了电压为-0.377V的情况下，卡尔曼滤波器的输出。其中“+”为观测值。程序注解写的很清楚很容易看懂。(Procedure describes the voltage of-0.377V, the Kalman filter output. Which+ For the observed values. Notes written procedure is easy to understand very clearly.)

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.
