IMC-based model reference adaptive control for IPM machines

A model reference adaptive control algorithm for interior permanent magnet machines is presented in this paper, in particular, the initial value of the adaptive control gains and the reference model are set based on the internal model control principle. Compared with the traditional model reference adaptive control, the proposed adaptive control law provides a better machine torque transient response and is robust to the machine parameter variation. The effectiveness of the whole system has been validated in a 40kW interior permanent magnet machine simulation platform.
