ONLINE MACHINE PARAMETER ESTIMATION FOR DIRECT TORQUE CONTROL

  • Yuri Plotkin HWR Berlin

Abstract

For DTC control monitoring the actual value of stator resistance is important. Based on previous investigations it is shown that the accuracy of online stator resistance monitoring of AC-machines fed by PWM inverters when using the superposition method suffers from dead time effects. A new and simple correction procedure is proposed to achieve high measurement accuracy without using temperature sensors. No additional hardware is required for this method. Experimental results are presented.
