| Abstract |
The paper deals with the problem of sensorless control of SRM drives. A speed control system using back EMF and position estimator is presented. The shaft position is estimated using a "global" current error. Such observer works well in closed loop - where all required mechanical signals are estimated. Observer presents good performance even though nonlinearity of SRM model. Moreover, that observer proves robustness against inaccurate motor parameter estimation. Proposed observer driven system tolerates wide range of inaccuracy of motor resistance estimation and proves a kind of toleration level to inaccuracy in motor inductance estimation. |
