| Abstract |
In this study, the new theory on ‘solar profile inverse function’, g(y), was defined for calculating the time(s) corresponding to solar profile angle. And the blind control algorithm with ‘solar profile inverse function’, g(y), and ‘solar profile function’, f(t), was proposed to improve the control performance. Within the boundaries of ‘optimum time interval’, ‘minimum time interval’, ‘maximum time interval’, ‘minimum blind movement’ and ‘maximum blind movement’, control algorithm with immediate decision of time and solar profile angle variations was proposed by using ‘g(y)’ and ‘f(t)’ without numerous iterative process. Through the implementation of proposed algorithm, concision, rapidity and accuracy of control could be improved. And then, the proposed ‘solar profile inverse function’ can also be utilized effectively in various field such as analysis of solar geometrical characteristics. |
