Abstract :
Brushless doubly-fed machines (BDFM) show potential benefits in adjustable speed drive systems by reducing converter rating and cost. While the BDFM system is open-loop stable, the resulting performance is far from optimum. Although closed loop scalar control is acceptable for some drive applications, fast dynamic controllers are needed for many drive systems. This paper introduces a synchronous frame model suitable for decoupled control development. Field oriented control algorithms are proposed and illustrated using simulation studies. Simulation results show good system response and an experimental system is being developed
