Field weakening nonlinear control of a separately excited DC motor [PDF]
First International Symposium on Control, Communications and Signal Processing, 2004., 2004 This paper investigates the design and implementation of nonlinear control schemes for a separately excited DC motor operating in the field-weakening region. A feedback linearization controller, a Corless-Leitman-type controller, and two nonlinear controllers are designed and implemented for a DC motor system. The stability of the closed-loop system is
