A Novel Flux State-based Control Method for Improved Dynamic Performance of Induction Motor

ABSTRACT

Induction machine (IM) is widely used in industries because of certain advantages. In previous research studies, investigations were completed to analyze the machine flux behavior in different reference frames such as Stationary and Park’s, however, the analysis and comparison for the wide-ranging machine flux behavior, in synchronously rotating stator field-oriented, and rotor-oriented reference frames, is not offered particularly during transients. In addition, the dynamically accurate torque and flux control is an essential requirement for high-performance induction motor drive. A number of techniques, including direct and indirect field-oriented control, direct torque and direct power control techniques, have been developed; however, most of them apply certain approximation criteria to optimize the linear system. It results in inaccurate tuning of respective current, torque and flux controllers, which deteriorates the dynamic performance. In this paper, a novel flux state-based nonlinear control method is presented which results in improved dynamic performance of induction motor drive. The proposed control method is simulated in the MATLAB/Simulink environment and experimentally validated on a 0.75 kW IM. The obtained results show the effectiveness of the proposed flux state-based control method for improved dynamic performance of induction motor drive.
