An optimization scheme for motor parameter adaptation in IFO vector controlled induction motor drive

Crucial to the success of the IFO vector control is the proper calculation of the slip frequency, which depends greatly on the motor parameters. Many schemes have been proposed for parameter adaptation in induction motor drives over the past years. However these schemes cannot be well applied in a practical drive system. In this paper, a new and practical scheme for motor parameter adaptation is proposed. This new scheme converts the adaptation problem into in optimization problem. A simple and reliable optimization algorithm that is expressly contrived for this application is employed to solve the optimization problem. Computer simulations and experiments are carried out to verify the proposed scheme
