Three-degree-of-freedom magnetic suspension mobile platform and control method thereof

The invention discloses a three-degree-of-freedom magnetic suspension mobile platform and a control method. The three-degree-of-freedom magnetic suspension mobile platform comprises a suspension platform, a driving unit, a magnetic stator, a position detection magnet, a three-axis sensor and a base, the suspension platform comprises a working platform and a suspension magnet arranged on the working platform; the suspension magnet is formed by superposing a plurality of cylindrical permanent magnets, and the suspension magnet is adsorbed on the working platform through an iron sheet base mounted on the working platform; the driving unit and the magnetic stator are detachably stacked up and down to form a suspension control assembly; the suspension control assemblies are fixed on the base and are opposite to the suspension magnets in number and position; the driving unit comprises a driving coil for controlling spatial three-degree-of-freedom motion, and the driving coil does not comprise a magnetic core or a p
