More Information
Summary:The invention discloses a relative coordinate transformation algorithm and detection system based on a three-freedom-degree spherical motor. A present direct cosine matrix is utilized to solve coordinates, a transformation matrix of a relative coordinate system, which is the coordinate system of a rotor relative to the coordinate system of a stator of the spherical motor, is derived, and the relative coordinate transformation algorithm is realized based on a hardware platform of the relative coordinate detection system based on the spherical motor. The calculated relative coordinate transformation matrix is measured and calculated further, and displayed in the same coordinate system in a 3D manner.
