PROJECT TITLE :

Torque ripple reduction and fast torque response strategy for predictive torque control of induction motors - 2017

ABSTRACT:

This paper proposes a simple control technique of induction motors (IMs) with improved dynamic response and steady-state performance by using a model-based mostly predictive control algorithm. The predictive torque management (PTC) technique analyzes the relationship between the electrical torque and stator voltage of IMs by using the stator voltage vector magnitude to get the reference voltage vector angle and accurately management the electrical torque. However, the traditional PTC method features a fixed reference voltage vector magnitude and so encompasses a large torque ripple within the steady state and slow dynamics in the transient state. The proposed PTC technique relies on mathematical equations, that enable minimization of torque error and calculation of a relevant reference voltage to establish a higher dynamic response in the transient state and accurate management performance within the steady state. Excellent steady-state performance and a fast dynamic response of the proposed method are proved by the simulation and experimental results.
