Other AbstractThe present invention relates to a control circuit for automatic navigation vehicle. Its circuit structure consists of differential amplifier, frequency-selecting filtering circuit, absolute value circuit and differencing and gain control circuits, and their connection is as follows: two coils of the navigation vehicle are connected with the differential amplifier, and then the following circuits are connected in turn, and its control circuit output is connected with an A/D converter. Because the magnetic conduct coils of the navigation vehicle are offset from magnetic field, the produced deviation signal is passed through the differencing circuit, and then is passed through the A/D converter, and is delivered into a computer-controlled servo system. Its frequency-selecting filter uses switching capacitor filter MF10. It has the advantages of small volume, light weight, high accuracy and good stability.
