Including architectural design、electrical design、system design, Green BIPV system design are analyzed, and the importance of the building fire and lightning protection design and the main points are pointed out. Further, the details of system design have also been given with specification and description. The photovoltaic system design elements and the importance are expounded through the photovoltalic project example analysis.

Based on fuzzy logic control adaptive bandwidth PLL design is presented for the problem of tracking poor stability and low accuracy when a certain type of radar tracking dynamic spacecraft. This method is mainly through fuzzy logic controller, adaptive level is determined by control rule of input respectively, and the outputs of rules are weighted combined to control the coefficient of loop filter, thus adjusting automatically the loop bandwidth, and enhancing the tracking stability of radar equipment and improving ranging accuracy. The simulation results show that the fuzzy logic control adaptive bandwidth PLL has higher tracking stability and accuracy.
