Abstract :
In this paper, we show that it is feasible to apply nonlinear MIMO feedback linearization technique to a separately excited DC motor system that is operated in high-speed field-weakening regime. Load-adaptive and sensorless control techniques to improve dynamic speed performance are proposed and compared. Also, application results are presented to verify theoretical ones.
