Research on the Coordinated Control Method to Obtain the Maximum Irradiation

This paper presents a form of concentrating the solar radiation-employing multi-mirror to reflect the sun´s radiation continuously on to the solar cell module. First, the basic structure, tracking control principles and methods of the Multi-Mirror concentrating solar radiation photovoltaic system are described. By the analysis of Multi-Mirror array of solar radiation concentrating system omnidirectional tracking control, the tracking movement equations of azimuth angle, tilt angle, space position of solar cell module and Multi-Mirror array are deducted. By establishing the tracking motion relationship between solar cell module and Multi-Mirror array, the tracking coordinated control between solar module and Multi-Mirror is achieved. The correlative quantitative analysis and numerical calculation are done for this system.
