Summary: | The invention relates to a volume kalman filter-based radial magnetic bearing displacement detection method and system. The radial magnetic bearing displacement detection method comprises the steps of obtaining radial displacement output signals and rotating speed signals of a rotor in an x direction and a y direction according to a continuous time system and discretizing the continuous time system to achieve extraction of displacement information of the rotor by a volume kalman filter algorithm. According to the volume kalman filter-based radial magnetic bearing displacement detection method and system, linear processing of a radial magnetic bearing which is a nonlinear model essentially is avoided; operation of a displacement-free sensor is achieved; the detection system has very high interference rejection capability; the radial magnetic bearing displacement can be accurately detected; and the radial magnetic bearing displacement can also be detected when the exact nature of the system is unknown.
