Comparative study of integral and classical backstepping controllers in IFOC of induction motor fed by voltage source inverter
A comparative study between Integral and Classical Backstepping IFOC structures of induction motor is proposed in this work. The Integral one is based mainly on a suitable combination of a nonlinear integral backstepping approach and an indirect field orientation control (IFOC). The first part ensures a global system stability using recursive Lya-pounov design and increases robustness despite disturbances and model uncertainties. The second part will guarantee flux orientation, decoupling, and current regulation. The effectiveness of the proposed control structure is validated by simulation as well as by experiment under critical disturbance conditions. Obtained results show a fast dynamic response, better load disturbance rejection capability, less parameters sensitivity and better tracking performance. (C) 2017 Hydrogen Energy Publications LLC.
