Abstract
The algorithmic structure of a vector controller capable of high quality speed control of a synchronous reluctance motor with and without the use of a rotor position sensor is presented in this paper. The controller is based on a conventional saturated machine d-q model. Its main merit is that it can be operated in a sensorless control mode by executing a new, very accurate parameter dependent algorithm for on-line estimation of rotor position and speed. The excellent performance of this scheme under maximum torque per ampere control is demonstrated by simulation and experimental results.
