This paper develops the application of a different control strategy to the vector control of the voltage-fed induction motor. The proposed model decomposes the control task into three loops, namely, the speed loop, the d-axis flux loop and the q -axis flux loop. Then, tracking of speed with different controllers is designed for each loop. Proportional- Integral update laws are used to adjust the control parameters, which increases the tracking performance (Z-N Method) .Simulations are obtained shows good robustness against parameter variations, high tracking performance and simplicity of implementation.

Vector Control Strategy

In this paper, a new vector control strategy is proposed to reduce torque ripples and harmonic currents represented in switching table-based direct torque control (ST-DTC) of a six-phase induction motor (6PIM). For this purpose, a new set of inputs is provided for the switching table (ST). These inputs are based on the decoupled current components in the synchronous reference frame. Indeed, using both field-oriented control (FOC) and direct torque control (DTC) concepts, precise inputs are applied to the ST in order to achieve better steady-state torque response. By applying the duty cycle control strategy, the loss subspace components are eliminated through a suitable selection of virtual voltage vectors. Each virtual voltage vector is based on a combination of a large and a medium vector to make the average volt-seconds in loss subspace near to zero. Therefore, the proposed strategy not only notably reduces the torque ripples, but also suppresses the low frequency current harmonics, simultaneously. Simulation and experimental results clarify the high performance of the proposed scheme.
