Nonlinear Control of an Induction Machine using Robust Controller based on H∞ Algorithm

Abstract:
Background and Objective: This study proposes a nonlinear feedback method and H∞ robust controller in order to assure a good decoupling, robustness performance and stability of the Induction Motor (IM) states. Methodology: By choosing the nonlinear dynamic model of the IM in a (d, q) synchronous reference frame, this study uses an input-output linearization approach and H∞ algorithm to define robust controllers in order to have a good regulation and convergence of the currents and then control independently the rotor speed and the flux. Results: The simulation results for a 5.5 kW induction motor are presented to illustrate the effectiveness and the high robustness of the proposed approach against parameter variations and disturbances. Conclusion: Thus, in the industrial applications, one will appreciate very well the use of a robust feedback decoupling strategy in order to control the currents and then preserve the robustness stability of an induction motor under disturbances.
