Signal detection

design and implementation of the control system of the electromagnetic navigation intelligent car are introduced.The magnetic field is analyzed on different path through Matlab

sensors’arrangement scheme is determined.Follow-up signal processing circuit is designed on the acquired signals.The signal sampling is completed

and the control strategy is determined.According to the runway signal collected by the sensors

SCM analysis is carried out through A/D transformation.The speed of the car is controlled by incremental PID through pulse width control steering gear to realize corner turn of intelligent car.Finally the fabrication of the electromagnetic navigation intelligent car which can operate on different paths steady and fast is realized.
