Analysis and Mitigation of Torsional Vibration of PM Brushless AC/DC Drives With Direct Torque Controller
The stator torsional vibration of permanent magnet brushless AC and DC drives is significantly reduced by the proposed novel direct torque control schemes for the first time. A new method to measure the torsional vibration mechanical transfer function by utilizing cogging torque for excitation is also reported. This world-leading research outcome has attracted the attention of Siemens Wind Power. Professor Zhu was subsequently invited to deliver a presentation on 1 Feb. 2011 and to host a one-day workshop in June, 2011. It leads to a joint UK Regional Growth Fund project with Siemens, £1,087,752 (50% funded by Siemens), 2012-2014.
