碩士 === 國立成功大學 === 航空太空工程學系 === 104 === This thesis combines the GPS tracking signals of Platalea minor with the 3D geomagnetic model to convert the geomagnetic information into the visual images along the migratory path of Platalea minor. The research employs the bionic technique to reconstruct the visual images of geomagnetism on the retina of Platalea minor in order to expound its magnetoreception navigation ability in the course of migration from Cigu district to the border area between North and South Korea. After elucidating the underlying principle of magnetoreception, the thesis proceeds to verify the feasibility of a bionic chemical compass according to this principle. To this end, we first establish the spin quantum dynamics for the radical pairs in magnetoreception molecules, and then apply the Lyapunov control theory to derive the desired magnetic field, which, when applied to radical pairs, can increase its sensitivity of magnetoreception. The proposed magnetic control law is successfully applied to a synthesized molecule called C-P-F to increase its ability of sensing weak magnetic field. The simulation results agree with the existing experimental data regarding C-P-F molecule and verify the feasibility of using C-P-F molecule as a bionic chemical compass.
