An Improved Analytical Dynamic Modeling of Hysteresis Motor

چکیده مقاله

Dynamic modeling of hysteresis motors is essential to predict of the transient performance, studying the dynamic stability and development of modern closed-loop control and estimation strategies. This paper develops a new analytic dynamic modeling for a high-speed, circumferential-flux type hysteresis motor in dq reference frame, The parameters of the equivalent circuit of hysteresis rotor material are adjusted based on operational B-H loop. For this purpose and based on elliptical assumption for B-H loops, the hysteresis lag angle β is updated due to the applied stator voltage and available load torque. Developed mathematical model satisfies many theoretical aspects of hysteresis motor behavior in transient and steady-state situations. Some simulations are provided to demonstrate the validity of developed model in Matlab/Simulink.
