Applying the estimation system for synchronization of thyristor rectifier operating from the permanent magnet synchronous machine

The use of adaptive estimator based on the flux linkage algorithm gives an opportunity to eliminate the speed sensor and rotor position sensor and to reduce the mass and dimensions parameters of the drive. Estimator provides the actual values of back electromotive force of the synchronous machine and that makes it possible to apply permanent magnet synchronous machine efficiently. The article presents the results of modelling of the permanent magnet synchronous machine operating on the controlled rectifier. The purposes are debugging of estimator algorithm, the comparison with the operating mode without estimator, as well as verification of the algorithm with the dynamic changes during generator operation.
