To improve the detection precision of angle position and realize the sensorless control for bearingless switched reluctance motors ( BSRM ) , a soft sensing method for rotor position is proposed by using least squares support vector machine ( LS-SVM ) based on left inversion system theory. The mathematical model of BSRM is transformed in state space. And then the rotor position soft sensing model is designed by left inversion soft sensing theory. Due to the nonlinearity and uncertainty, LSSVM is used to identify left inversion soft sensing model and implement the detection of BSRM rotor position. The numerical simulations show the proposed soft sensing model can achieve real-time and accurate rotor position detection.
