Improved scalar control using flexible DC-Link voltage in Brushless Doubly-Fed Reluctance Machines for wind applications

In this paper, we propose to investigate the capability of Brushless Doubly-Fed Reluctance Machine and its potential to drive speed in various domains based on synchronous-speed as the main reference, however, that requires modernizing the control algorithm in order to comply with the new requirements. This flexibility in speed performance of this machine requires further observation from applicable controller to cover the necessary change occurring in various speed domains. Controllable DC-link voltage is considered to be one of qualified control theory which brings a significant improvement to the performances of scalar control algorithm related to BDFRM.
