Robust Control of Induction Motor with H∞ Theory based on Loopshaping

다국어 초록 (Multilingual Abstract)

The H_∞ approach, adopted in this paper, is based on loop shaping using a normalized coprime factor combined with a field-oriented control to control induction motor. We develop two loops.
The first one, the inner loop, controls the stator current by H_∞ controller in order to obtain good performance.
The second loop, the outer one, guarantees stability and tracking performance of speed and rotor flux using a proportional integral controller. When the rotor flux cannot be measured, we introduce a flux observer to estimate the rotor flux. Simulation and experimental results are presented to validate the effectiveness and the good performance of this control technique.
