Research on the approximate model of optoelectronic system

Abstract

With the development of science and technology, all kinds of systems have been established and simulated. The photoelectric system is also a great influence on the daily life. At present, there are many methods to establish the model of photoelectric system, but the best method is the most important one.We need to establish a precise mathematical model of the photovoltaic system, in order to make a comprehensive study of the optoelectronic system.

This paper firstly introduces the main concepts of photoelectric system and its development trend in the future. The core technology of optoelectronic system is made up of photoelectron. The electronic method used by the photoelectric system to process and control the optical information, the basic function is to convert the received optical radiation into electrical signals, and use it to achieve some practical purposes. In life, there are many such examples, such as photovoltaic power generation, photoelectric sensors and so on.

Then based on the study of solar photovoltaic battery model with MATLAB, for the characteristics of photovoltaic cells, the establishment of its model and simulation were studied in a series of.

Then the difference approximate method the mathematical model is discussed, detailed introduces the standard deviation evolutionary algorithm and its characteristics, then the difference approximation algorithm is improved and change the parameters or variables or other algorithm combining, ,analysis of the effect of different factors on the photovoltaic cells, and draw the graph compares the results more clearly.try to get a better result as the approximate model, on the study of the optoelectronic system model discussed.

At last, the method of establishing the system model with each component model is summarized, and the prospect of the research on the optoelectronic system model is

discussed.
