A new high performance sensorless speed vector controller that implements the maximum torque per ampere control strategy for the inverter driven synchronous reluctance machine is presented in this paper. It is based on a parameter dependent technique for on-line estimation of rotor position and angular velocity at the control rate. The current ripple principle is used to estimate position. The estimates are fed to a conventional closed-loop observer to predict the new position and angular velocity. The very high accuracy of the sensorless control algorithm at both low and high speeds is confirmed by experimental results.
