Man-machine interaction control method for space universal rotating magnetic field

Abstract

The invention belongs to the technical field of automatic engineering, and discloses a man-machine interaction control method for a space universal rotating magnetic field. Man-machine interaction control of the direction of the rotating axis of the space universal magnetic field is achieved by applying a same-frequency sinusoidal signal current type space universal rotating magnetic field superposition formula with side sway and pitch angles of the axis of the magnetic field in a longitude and latitude coordinate system as related amplitude values and phases of input variables to a three-axis orthogonal nested Helmholtz coil device, controlling the side sway and pitch angles in a separated mode through two control rods respectively, forming the rotating magnetic field with the axis capable of being independently scanned in the directions of the side sway and pitch angles in the uniform area surrounded by the three-axis orthogonal nested Helmholtz coil device in an overlapped mode, and regulating the side sway and pitch angles of the axis of the magnetic field according to wirelessly-transmitted images of a camera at the front end of a capsule robot. Independent scanning of the robot in the two directions of side sway and pitch is achieved, the man-machine interaction operation is simple and rapid, and posture adjustment and rolling operability of the robot in the bent environment is improved.
