“…where M, I 1d , and I 1q represent the mutual inductance, d-axis current, and q-axis current, respectively. When the slip-angular-frequency command changes steeply, the q-axis secondary flux fluctuates transiently, and the coupling of the secondary flux occurs [11], [12]. Various control applications, such as autodisturbance-rejection control [13], morel reference adaptive system [14], sliding-mode control [14], [15], and neural networks [16], [17], [18], have been proposed to improve the current response.…”
