Flux oriented control without using rotor time constant and stator resistance

Flux oriented control systems of induction machines are sensitive to the variation of the machine parameters such as rotor time constant and stator resistance. Speed estimation has been proposed by many papers however they depend on the variation in rotor time constant and stator resistance. A system that has speed estimation and is also independent of rotor time constant and stator resistance is desirable. This paper adapted the methods proposed by G. Yang and T. Chin (1989) and K. Tungpimolrut (1994) and investigates and extends these strategies in rotor flux oriented control. The authors discuss the rotor flux observer and the reactive power model reference adaptive system.<
