First the passivity of motor rotor flux subsystem is proved. Workless forces have no influence on the energy balance equation and have no effect on the asymptotic stability. Then it is discussed that the system can stably track the reference rotor flux without rotor flux observer. At last an adaptive PBC strategy is proposed with regard to the rotor resistance change. A clear and simple design for the speed control subsystem with inner current loops is presented.
