SENSORLESS SYNCHRONOUS MOTOR CONTROL SYSTEM
Electrical and data processing facilities and systemsRelevance Rotor position sensors are used to measure the transmission speed of electric motors and determine rotor positions. Thanks to this sensor, it becomes possible to control the speed and rotor both in the starting mode of the electric motor and in normal operation.

Estimation of Saturation of Permanent-Magnet Synchronous Motors Through an Energy-Based Model [PDF]
, 2011 We propose a parametric model of the saturated Permanent-Magnet Synchronous Motor (PMSM) together with an estimation method of the magnetic parameters. The model is based on an energy function which simply encompasses the saturation effects. Injection of

Randomly pivoted Cholesky: Practical approximation of a kernel matrix with few entry evaluations
Communications on Pure and Applied Mathematics, Volume 78, Issue 5, Page 995-1041, May 2025.Abstract The randomly pivoted Cholesky algorithm (RPCholesky) computes a factorized rank‐k$k$ approximation of an N×N$N \times N$ positive‐semidefinite (psd) matrix. RPCholesky requires only (k+1)N$(k + 1)N$ entry evaluations and O(k2N)$\mathcal {O}(k^2 N)$ additional arithmetic operations, and it can be implemented with just a few lines of code.

Slip Estimated Sensorless Vector Controller [PDF]
The Journal of the Korean Institute of Information and Communication Engineering, 2010 A sensorless vector control of an induction motor provides a good performance in the middle and high speed region. However, in the low speed region, it is very difficult to implement the sensorless vector controller because the feeding voltage measured by the motor is very low. In this paper, we designed the sensorless vector controller of an induction
