“…4(b) and 4(c)). It was shown in [5] that the FOC will be unstable when R s and R r are much larger than the nominal values, R sn and R rn . Consequently, the proposed SMLTC is robust to variation of the resistance parameters and improves the drawback of the FOC.…”

This paper proposes a sliding-mode linearization torque control (SMLTC) for an induction motor (IM). An ideal feedback linearization torque control method is firstly adopted in order to decouple the torque and flux amplitude of the IM. However, the system parameters are uncertainties, which will influence the control performance of the IM in practical applications. Hence, to increase the robustness of the IM drive for high-performance applications, this SMLTC aims to improve the immunity of those uncertainties. We modify the flux observer of Benchaib and Edwards [15] by means of the adaptive sliding-mode method. This not only eliminates the estimation of the uncertainty bounds, but also improves the performance of sliding control. In addition, a practical application of the proposed SMLTC, with a model reference adaptive control (MRAC) scheme incorporated as the inner and outer loop controller used for position control, is also presented. Some experiments are presented to verify the control theory and demonstrate the robustness and effectiveness of the proposed SMLTC.

“…Tuning procedures based on the idea that broader stability margins give rise to smoother operation are discussed in Chang et al (2000). A variety of unstability phenomena has been the subject of several papers (Gordillo, Salas, Ortega, & Aracil, 2002;Harnefors, 2000).…”

“…The case of three-phase machines has been explored in Chang et al (2000), where a tuning procedure for the PI is presented based on the idea that broader stability margins give rise to smoother operation. The case of a five-phase drive with harmonic injection is more complex because of the addition of new degrees of freedom.…”

“…It is clear that the rotor resistance might vary from its nominal value significantly with a considerable impact on the system performance. Taking this into account, Chang et al [10] proposed, and also experimentally validated, tuning rules for the proportional plus integral (PI) feedback gains to achieve good tracking performance under a wide range of variations of the motor parameters.…”

the mean of the produced torque to be equal to the command torque. Fig. 3(c) shows the average switching frequency of both schemes; the conventional DTC scheme shows considerable variation in frequency which has been effectively controlled in the duty-cycle control scheme. Fig. 3(d) shows the duty cycle calculated by the torque-ripple reduction scheme. VI. CONCLUSIONA simple scheme has been presented for duty-cycle control in a DTC-based induction motor drive. The scheme has been shown to reduce the torque ripple produced by this kind of drive, particularly at low speeds. The scheme has also been shown to effectively control the mean of the output torque and to limit the switching frequency variation.

BriceAbstract-A passivity-based controller, which takes into account saturation of the magnetic material in the main flux path of the induction motor, is developed to provide close tracking of time-varying speed and flux trajectories in the high magnetic saturation regions. The proposed passivity-based controller is experimentally verified. Also, a comparison between the controllers based on the saturated and nonsaturated magnetics is presented to demonstrate the benefit of the controller based on the saturated magnetics.
