摘要
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.
