The knowledge of electrical and mechanical parameters of high-performance electromechanical drive systems is of paramount importance for designing high-performance controllers and/or developing accurate simulation models. By high-performance control is meant least torque (position) ripple for torque (position) control. Machine parameters are typically load and temperature dependent. This makes their...
The sensorless position control of permanent magnet motors can be successfully implemented by superimposing a high-frequency voltage on the control voltage. The accuracy of the method relies on a fast and accurate signal processing of the measured quantities and on the compensation of the inverter and motor non idealities. In this paper the position estimation is obtained by adding a high-frequency...
