双轴太阳跟踪系统运动控制规律的研究

Study on Motion Control Law of 2-axisSun Tracking System

基于太阳位置计算模型,采用矢量分析方法,通过地平坐标系、时角坐标系、跟踪坐标系间的坐标变换,建立了太阳位置与时间、跟踪系统运动与太阳运行位置间的对应关系,并建立了视日运动轨迹跟踪方式——双轴太阳跟踪系统运动控制方程。对其运动特性进行了分析,在此理论分析基础上开发了双轴太阳跟踪控制系统程序,实现了双轴太阳跟踪系统的自动跟踪。

Based on the geometrical model for calculating the sun position, the relationships between the sun position and time and the movement of the tracking system and the sun position are set up with the help of the vector analysis method and the transformation of different coordinate systems, i.e. the horizontal coordinate system, the equatorial coordinate system and the tracking coordinate system. The motion control equation of the 2 - axis sun tracking control system is derived on the basis of control strategy of the apparent motion of the sun and the motion characteristics analyzed. As a result, he programs of the 2 - axis sun tracking control system are developed so as to realize the automatic tracking of the 2 - axis sun tracking control system.
